* Remove redundant `verifier.done()` call
This `done` call completes the verification process and stops it responding
with further messages. It is unnecessary, *provided* the verification completes
successfully, for which see
https://github.com/matrix-org/matrix-js-sdk/pull/3382.
* Remove duplicated code in `decryption-failure` test
* remove unused imports
