Merge branch 'fix-path-with-leading-dot-error' into 'master'

Fix error preventing displaying of commit data for a directory with a leading dot

Directories with leading dots erroneously get rejected by the route controller if git
ref regex is used in constraints. This prevents commit data from being loaded. The regex verification is now done in controller.

Closes https://github.com/gitlabhq/gitlabhq/issues/8763
