Convert widget OIDC exchange dialog to TS (fixing it)

Fixes https://github.com/vector-im/element-web/issues/15631

The `super` call was the primary issue, but a log line in the `onPermissionSelection` was also using the wrong property. Both issues have been fixed as part of the TS conversion in order to make the thing compile, conveniently fixing the bugs.
