[wundergroundupdatereceiver] Bugfixes: Regenerate trigger channel with proper type and more metadata. Normalize channel names. It might be easiest to delete and allow recreation of channels. (#13327)

* [wundergroundupdatereceiver] LAST_QUERY parameter should not be mapped automatically
* [wundergroundupdatereceiver] All channeltype props need to be applied
Especially the channel kind
* [wundergroundupdatereceiver] Remove illegal characters from channel name

Additionally expand the channel naming test to assert the generated channelUID and test that _ in names isn't inadvertently replaced

* [wundergroundupdatereceiver] Don't default AutoUpdatePolicy on creation
* [wundergroundupdatereceiver] Migrate changed channel to trigger type
