fix(call): leave call along with room (#33162)

* make sure to disconnect from possibly active calls for a room when leaving the room

* log error on log call

* Update apps/web/src/utils/leave-behaviour.ts

Co-authored-by: Michael Telatynski <7t3chguy@gmail.com>

* fix wrong logger import

* hang up calls properly on empty rooms for both legacy and element calls (listen for room event and leave call if only one member left). add tests for both legacy and element calls.

* format Call-test.ts

* revert async on function def

* revert Call.ts and Call-test.ts. Wrap legacy call hangup in try
