mod_rest: Reject password that fails saslprep earlier (thanks tgy) Prevents an error later if/when passing the password through saslprep a second time in the authentication module, since the prep functions now reject nil The error reporting could be improved but that would involve adding a way to pass errors back out of the check_credentials() function.
