fix(scripts): Match full client name when disabling

This fix prevents "pivpn -off" from failing to disable a client when another client is already disabled and the disabled client name starts with the client name you're trying to disable.
e.g. "user-1" wasn't able to be disabled if "user" was already disabled.
