Fix and test leave project display
The 'Leave this project' display on project page was broken. It was calling the method incorrectly, which returned `nil` and displayed nothing.
This fixes the display and also adds 2 different tests for it.

Sidekiq-cron configuration moved to gitlab.yml
When `sidekiq-cron` was introduced, jobs configuration where placed
in `schedule.yml` file.
As discussed in #3928, this is not desirable.
We moved it to `gitlab.yml`, exposing only the "cron" part of the configuration.

Allow account unlock via email
We see a lot of users get confused about what it means when your account gets
locked. Many try to reset their password and are still faced with a lockout.
With this change, users receive an email that allows them to unlock their
account immediately. The previous behavior where the account is auto-unlocked
after a time also still works.

Do not display project group/name when issue and MR are in same project
I noticed that things seem a bit cluttered for related merge requests
when displaying the group/project name for every item, even when it's
in the same project.
For merge requests that are in the same project as the issue we probably
don't need to display the 'in group / name' bit.

Right now, creating a branch or tag is only possible on the project page dropdown or on the commits page. This merge request both actions to the tree header dropdown.
