Sort out what we wait for after login 

We were waiting only for the client to become logged in rather than
for setLoggedIn() to finish but then we were waiting for the first
sync to complete which is far longer. We need setLoggedIn to have
finished for crypto to be set up so we can query cross-signing keys,
so just wait for that anyway, the logic becomes a lot simpler and
we're waiting the same amount of time because we have to wait for
the first sync to finish. We can also download keys in parallel.
