* Handle case of encryption key for an index to be undefined
As per https://github.com/matrix-org/matrix-js-sdk/pull/4423 the key can be undefined and so we should handle this rather than waiting for SubtleCrypto.importKey() to fail.
* Use release version of matrix-js-sdk
Diff is baa6d13506...v34.7.0
* Use RTCSession. reemitEncryptionKeys()
* Add some test coverage whilst we are here
* Add some test coverage whilst we are here
* Lint
