test: Add integration tests for saving external userglobal storages

As the external storage uses the Nextcloud server itself the number of
workers of the PHP process running the Nextcloud server had to be
increased. Otherwise if a request is sent for the external storage while
handling a request from the integration tests a deadlock would occur.
