Does not start without Context Setting.

[Rabbit234]

Is there any way to get this extension working without using the context setting? I use subsonic with Apache reverse Proxy and my domain looks like this:
https://music.example.com/

If you start it without context setting it says:

WARNING Found subsonic configuration errors, the extension has been automatically disabled:
WARNING subsonic/context must be set.
WARNING Please fix the extension configuration errors or disable the extensions to silence these messages.

I managed to change the context of my subsonic server to https://my-domain/subsonic.
Now I'm getting the following error during start-up of mopidy:

When I put "/" as the context, it seems to start fine (is listed in enabled extensions), but I still don't see anything about subsonic in gmpc nor ncmpcpp

EDIT: had to use the git version of mopidy-subsonic with this patch: #13 (comment) and my config is now

[subsonic]
hostname = mysubdomain.subsonic.org
port = 80
ssl = no
context = /
# etc.

Note that I have ssl=no and port=80 even though the site itself is port 8443 with ssl (it won't find the redirect from subsonic.org if you specify port 8443 at first).

added that to #19
