* Check for `unknown variant` on to-device sending and fallback to room event encryption.
* fix tests
* fix error js-sdk api type
* Change logger from debug to warn for unsupported to-device transport and improve error message comments
* also add case for not supported
This will be send by the driver in case we sent an encrypted to-device but do not have support of that.
