Upgrade to Matrix SDK latest (Store Rewrite) and Tokio 1.0 

This upgrade introduces a handful of breaking changes in the Rust
Matrix SDK.
 - Some types have disappeared and changed name.
 - Some functions are no longer async.
 - Room display name now has a Result type instead of just returning
   the value.
 - Client state store has breaking changes (not really a big deal).

This required introduction of a new type to store room information
that we are interested in on the context struct. This new RoomContext
is required mostly due to unit tests, because it is no longer possible
to instantiate the Room type in the Matrix SDK.
