Fix "useless assignment" Rubocop warnings

Fix bug where transferring a project would result in stale commit links

Transferring a project to another namespace updates the project's updated_at
field, but since the cache key did not depend on the object, the page fragments
were not invalidated. This resulted in stale links to the commits. Changing
the cache key to use the project pathname solves this issue.

Improve project page height

old thing. Grey block not aligned to the bottom. It was a scroll even with short project description.

Ensure GitLab CI project exists when CI service is activated manually

When I check activeated checkbox in project services for GitLab CI it
cause half-working state when gitlab_ci_project is missing. This patch
fixes it until we have proper behaviour implemented later

This fix also bring us to the point when fork of project is a bit broken and have unnecessary code so I made cleanup.

Add last push widget to starred projects dashboard

This adds the last push widget to the starred projects dashboard. If a user set the starred projects dashboard as their preferred dashboard they would not see last push widget. The look is seamless between starred and 'your projects' dashboards.
