Look for 'gitolite_admin_uri' in the right section

of 'gitlab.yml'.

gitlabhq\config\initializers\1_settings.rb looks for
'gitolite_admin_uri' in the 'git' section of 'gitlab.yml'

Actually, that setting is in the 'git_host' section.
If not fixed, the 'gitolite_admin_uri' would always be equals to
'git@localhost:gitolite-admin', even if the administrator wants
to have another user than 'git' in charge of that repo.
