Use latest/master version of matrix-registration

v0.7.0 is broken right now, because it calls
`/_matrix/client/r0/admin/register`, which is now at
`/_synapse/admin/v1/register`.

This has been fixed here: 6b26255fea

.. but it's not part of any release.

Switching to `master` (`docker.io/devture/zeratax-matrix-registration:latest`) until it gets resolved.
