Fix archive corruption

* When I click download I trigger archive creation
* We don't use tmp storage for uncompleted archive
* When I refresh a page - archiving still in progress but file already exists - I get corrupted (unfinished) file
* If I wait for few more seconds and click download - I get correct file because archiving operation finished and file is valid

This MR fixes issue by bumping `gitlab_git` to newer version. In this version archive created in tmp file and becomes available only when archive operation finished.

Fixes #1394

Remove source button checkbox always try to remove branch in target
project. For fork source & target projects are differents - so we hide
checkbox from UI. After MR accepted you can easily remove branch with
'Remove branch' button that do remove branch call to valid project
