Added bottom margin to CLI instructions

The CLI instructions block in the empty project page is missing a margin-bottom style property. I added it, you can review the only line I edited to add this.

This only fixes a UX bug (to me), related to the "Remove project" button that is not correctly padded. Now I believe that part look better :)

I attach screenshots.

also be attached to a block.

Fix Error 500 after renaming a project path

Renaming the path of a project would result in an Error 500 due to `@repository` being memoized with the old path. An Error 500 would result:

Upgrade bundler-audit from 0.4.0 to 0.5.0

Bundler Audit can now run the `check` command with an `—update` flag to update the Ruby CVE repository before checking. This removes the need for two separate commands in GitLab CI ([source](https://github.com/rubysec/bundler-audit#synopsis)).

See the Changelog for more information: https://github.com/rubysec/bundler-audit/blob/master/ChangeLog.md#050--2015-02-28
