Fixes https://github.com/status-im/status-desktop/issues/15930
The issue happened because I received a notification about a contact request, but the request was not associated with a message in the DB. The DB didn't have a message with the required ID in it.
This potential fix moves the creation of the contact request later in the handling code, because the only way this bug can happen as far as I see it is if there is an error later in the handler function and the message is never added to the response, and therefore never saved.

History
Originally this package was a dedicated repo called status-protocol-go and was migrated into status-go. The new status-go/protocol package maintained its own dependencies until sub modules were removed and the root go.mod file managed all dependencies for the entire status-go repo.
