Protected Branches not working for imported repos

Created by: rodgerramjet

Summary:

Imported repository doesn't enforce protected branches. See #3544 (closed) - similar problem. Whats different from 3544 is that I have the symbolic link for the update hook defined.

If I create a fresh repo and test the same process with the same user, it (correctly) blocks pushes to the master branch which tells me that its not a problem with the users setup.

Steps to reproduce:

Import (following steps from https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/raketasks/import.md)
I imported a repo using gitlab-rake gitlab:import:repos
add user as developer to project
Ensure user isn't an Admin on project, etc
Push using git cli with appropriate thumbprint for the developer

Expected behavior:

[remote rejected] master -> master (pre-receive hook declined)

Received behavior

d13fbf7..28f8efc master -> master Branch master set up to track remote branch master from origin.

Observations

Checked the symbolic link on both repositories - they are pointing at the same script
