DeleteRef: add missing permission check

Browse Source 
This commit adds the missing permission check when delete a single
branch through the "Delete Branches" endpoint. The permission
check is forgotten because DeleteRef#deleteSingleRef assumes the
caller has done it before. But "Delete Branches" didn't do that.

It's created just for this stable branch. For "master", it's fixed
by I6a7f48e4a9. Cherry-pick is hard because these classes have been
refactored to other packages.
