Removed User#project_relations

This is to make things more compatible with EE so merging is easier.

cc @dzaporozhets 

See merge request !3192

GitLab EE adds an extra relation that selects a "project_id" column
instead of an "id" column, making it very hard for this method to be
re-used in EE. Since using User#authorized_groups in
ProjectsFinder#all_groups apparently has no performance impact we can
just use it and keep everything compatible with EE.

Filter import_url params because they may contain auth information. Fixes #14199

cc @dzaporozhets @DouweM tagging you since this is security related.

Fix importing PR's from GitHub when the source repo was removed

Closes gitlab-com/support-forum#584

Disallow blank (non-null) values for a Note's `line_code` attribute

It's unclear how these blank values got added, but GitLab.com had a few:

```
irb(main):002:0> Note.where("line_code IS NOT NULL AND line_code = ''").count
=> 439
```

We've added a migration to convert any existing records to use a NULL
value when blank, and updated Note to set blank values to nil before
validation.
