Removing repository unlinks issues from changesets for all projects
A bit rare problem.
1. Let we have two projects linked to one SCM repository (same filesystem path to the checkout).
2. Let we have issues in those projects references by changesets. They can be seen at 'Associated revisions' tab.
3. Delete one repository from the project settings
4. After this, all issues are unlinked from changesets (`issues.changesets` is empty).
Issues are linked to changesets.
All issue-changeset references are lost.
I think `scan_changesets_for_issue_ids` must be called after removing repository that is linked to more than one project. I called it from the console and it helped.
