Cancel verification request if input secure key

[richvdh]

After a succesful login into the application, iOS will automatically send a verification request to any other existing devices. If the user verifies by entering their secure passhprase / secret key instead, it does not automatically cancel the verification request sent out to other devices.

As a result, even once the device is verified, other devices may still see a "Accept verification request" dialog

@richvdh If this goes for EXI, then I think there is no longer any automatic sending of verification requests, only when the user initiates it. Perhaps can be closed?

I'm afraid I don't have any particular context on this issue: I just converted it from a draft issue that was on our board.

Note that it's filed against element-ios, not EXI, however.
