Simplify references to `VerificationRequest` (#11045)

* Use new `VerificationRequest.getQRCodeBytes()`

* Use new `VerificationRequest.otherDeviceId`

* Remove references to `VerificationRequest.channel`

* Replace references to `VerificationRequest.{requesting,receiving}UserId`

Normally these are guarded by `request.initiatedByMe` so we can trivially
replace it with `request.otherUserId` or `client.getUserId()`. In one place we
actually need to apply some logic.

* increase test coverage

* Even more test coverage

* Even more test coverage
