Fix server error when editing a note to "+1" or "-1"

### Summary

If a user edits a comment with "+1" or "-1" in the beginning, the POST returns an Internal Server error. (issue #1151). This merge request resolves that error.

### Steps to reproduce

1. Comment on an issue with "Test comment".
2. Edit the issue.
3. Write "+1" and click "Save Comment".

### Expected behavior

The edited note should be saved and refreshed. Any previous upvotes/downvotes from the user should contain a strikethrough.

### Observed behavior

Internal Error

### Fix

It turns out no tests were present for the "Edit Issue" functionality. I added spinach tests to exercise this and reproduced the error.

Most of the routes in `notes_controller.rb` appear to render all notes for the given discussion. `_form.html.haml` needs the full list of notes commented by the user to add strikethroughs for older upvotes/downvotes. However, only the `index` route appeared to obtain this information. The fix is to add a `before_filter` to obtain all the user's notes beforehand, except in the delete case where this information is not needed.

Things to watch: `NotesFinder` needs `target_type` and `target_id` to determine what to do. I'm not sure if there is a conscious effort to phase these keywords out in favor of `noteable_type` and `noteable_id`.

Don't leak information about private project existence via Git-over-SSH/HTTP.

Fixes #2040 and https://gitlab.com/gitlab-org/gitlab-ce/issues/343.

Both `Grack::Auth` (used by Git-over-HTTP) and `Api::Internal /allowed` (used by gitlab-shell/Git-over-SSH) now return a generic "Not Found" error when the project exists but the user doesn't have access to it.

Don't show Unassigned in user select when searching.
