Wait for a room with joined state in /sync after creating it

[jmartinesp]

Content

Rename RustMatrixClient.awaitRoom to RustMatrixClient.awaitJoinedRoom and make it actually wait on receiving the expected room with a joined membership state.

Motivation and context

Fixes (or workarounds) #3183 . iOS seems to have their own counterpart.

Tests

Create several rooms one after another. None of them should display the room preview screen that was incorrectly displayed before, as the received room still didn't have the right membership state.

This patch works like a charm.
I created 5 rooms in a row. Every time, it went as expected. Thanks @jmartinesp !

Makes sense, but would be great to have something to wait for a room or subscribe to room membership in the rust sdk!
