* Always consider multi-SFU mode enabled when using sticky events

CallViewModel would pass the wrong transport to enterRtcSession when the user enabled sticky events but didn't manually enable multi-SFU mode as well. This likely would've added some confusion to our attempts to test these modes.

* Fix test type errors

* add todo comment
