homescreenhandler: Avoid using a stale wl_outputsandbox/mvlad/update-homescreenoctopus

Rather than storing wl_output when creating a HomeScreenHandler object,
retrieve the output at activation. Presumably, we could use Screen and
from there get it but seems to be easier this way.

Re-plugging the connector back and forth would result in a stale wl_output,
so this would retrieve it always as the currently enabled/active one.
