Modified the `repo_dump` and `repo_restore` rake tasks to properly dump and restore repositories based on their `path` rather than their (project) `name`. The project name can be uppercase and may contain spaces. This caused the repository to be restored as a different `path` that it was initially created as, thus, breaking the `git remote` and the web interface can no longer detect the repository either because it searches by `path` and not by `name`. Also, when restoring the permissions are incorrect making it impossible to push new commits to the remote repository. So now on success it'll set the correct permissions (but requires that the `gitlab` user has `sudo` privileges, or this task must be executed as root).

Improve handling of misconfigured LDAP accounts.

Gitlab requires an email address for all user accounts as this is the
default account id and is used for sending notifications. LDAP accounts
may be missing email fields so handle this by showing a sensible error
message before redirecting to the login screen again.
