Fix redirect loop by using dummy albums domain

Instead of trying to match the albums host with current host
(which always fails in path-based routing), use a dummy domain
'albums.localhost.invalid' that will never match the actual host.
This prevents the automatic redirect to /shared-albums.

Version bump to 0.3.2
