* Retry to-device messages
This adds a queueToDevice API alongside sendToDevice which is a
much higher-level API that adds the messages to a queue, stored in
persistent storage, and retries them periodically. Also converts
sending of megolm keys to use the new API.
Other uses of sendToDevice are nopt converted in this PR, but could
be later.
Requires https://github.com/matrix-org/matrix-mock-request/pull/17
* Bump matrix-mock-request
* Add more waits to make indexeddb tests pass
* Switch some test expectations to queueToDevice
* Stop straight away if the client has been stopped
Hopefully will fix tests being flakey and logging after tests have
finished.
* Add return types & fix constant usage
* Fix return type
