Peter E Conn and Commit Bot 🤝 Ensure TWA provider is verified for notification delegation.
In https://chromium-review.googlesource.com/c/custom-tabs-client/+/1422138
origin verification may occur but without calling the callback (if it
is done implicitly by Chrome instead of explicitly by the client).

Move setting the trusted provider to a place where it will be called.
