Exclude some pending or inactivated rows in Member scopes

An unapproved request or not-yet-accepted invite should not give access rights. Neither should a blocked user be considered a member of anything.

One visible outcome of this behaviour is that owners and masters of a group or project may be blocked, yet still receive notification emails for access requests.

lib/backup: fix broken permissions when creating repo dir

## What does this MR do?

This MR fixes an issue where gitlab:backup:restore will not work because the repositories directory is set up with bad permissions. The bad permissions will prevent access to the repositories by the git user, causing all kinds of troubles (e.g. gitlab-shell won't install hooks).

## Are there points in the code the reviewer needs to double check?

## Why was this MR needed?

Rake task gitlab:backup:restore would complete successfully, but gitlab:check will report errors and gitlab cannot access repos.

## Screenshots (if relevant)

* repositories.old.1472478726 was created without the fix
* repositories was created with the fix

Fix attribute inclusion import/export config ignored in some cases

In the `import_export.yml` file we define the inclusion of some of the attributes. For some reason, this isn't working in certain cases - very unfortunate this includes `user`. This has been introduced in 8.10.3.

Add a data migration to fix some missing timestamps in the members table (again)

Repeats an earlier migration to fix historic bad data in the members table (missing created_at and updated_at fields)

I'm expecting the WHERE clauses to be fast enough, and to return few enough rows, that the migration doesn't need to use batches, but I'm not too familiar with the size of these tables in the wild, so perhaps that's a poor assumption.

8.10 introduced a dependency on the  `members.created_at` field in the project and namespace member view. If bad data is present, viewing the list of members now results in an NoMethodError and a 500 response from GitLab. Although the previous migration should have fixed all bad rows, we have evidence that it didn't in at least one case, despite the migration claiming to have run in the past.

## What does this MR do?

Catches IPAddr::InvalidAddressError exceptions in `trusted_proxy?` when a) a trusted proxy is set up in the gitlab config and b) an invalid IP address is passed to the method (e.g. one with a port attached). When caught, returns `false` from the method. Prevents a 500 error in this situation.

Fix attr reader to force the intended values for source and target shas

## What does this MR do?

When importing a pull request from GitHub, the old and new branches may no longer actually exist by those names, but we need to recreate the merge
request diff with the right source and target shas.  We use these `target_branch_sha` and `source_branch_sha` attributes to force  these to the intended values. But the reader methods were always looking up to the target/source branch head instead of check if these values was  previously set, this MR applies a memoization pattern to both of them.

## Are there points in the code the reviewer needs to double check?

This [commit](https://gitlab.com/gitlab-org/gitlab-ce/commit/6ce25e7b4caa9e94de74378729178c7060d640b2) introduced this bug in the importer.

Properly abort a merge when merge conflicts occur

If somehow a user attempted to accept a merge request that had conflicts (e.g. the "Accept Merge Request" button or the MR itself was not updated), `MergeService` did not properly detect that a conflict
occurred. It would assume that the MR went through without any issues and close the MR as though everything was fine. This could cause data loss if the source branch were removed.

Add a log message when a project is scheduled for destruction for debugging

We have a lot of projects that are in `pending_delete` state. It's not clear whether they were ever scheduled for destruction, or whether Sidekiq just dropped the job due to `MemoryKiller` or some other reason.

Also this will provide a record of which user destroys a project.
