fix(calls): no "the shared window was closed" toast when an admin turns sharing off (#297)

When a room admin turned off Allow Screen Sharing, the sharer got two
toasts: the correct "turned off by a room admin" and the fork's
"ended" notice, "the shared window was closed", which was wrong. Skip
the ended notice while the room policy forbids sharing.

Fixes #297
