* Improve logging in `DeviceListener`
Sometimes we get a logline `4S is missing secrets` but it's hard to see *which*
secrets are missing. https://github.com/matrix-org/matrix-js-sdk/pull/5054
added a method to the js-sdk which allows us to get more info: use it here.
* Use getSecretStorageStatus for analytics reporting too
* Fix unit tests
Any UTs for vector-web layer components or functionality should go here.
This used to contain the UTs for notifications before they got moved to react-sdk.
