Fix Rspec error when using non-default port

Prevent test failures when GitLab is configured to use a port other than
80.
Use actual GitLab URL for test assertion

Assert the full GitLab root URL, including the port, instead of using a
regexp to tolerate whatever port is returned.
Use argument list for sh instead of string

Faster, more portable and less error prone since no shell expansion.
