Subject: [PATCH] Fix invalid matrix-postgres.service when
 matrix_postgres_process_extra_arguments is empty

This only seems to be affecting some people badly enough to cause
matrix-postgres not to start. Certain systemd versions probably handle
it better or something.

Fixes https://github.com/spantaleev/matrix-docker-ansible-deploy/issues/889
(hopefully)
