Bug 1573254: Part 2 - Update tests to await snapshotWindow when necessary. r=mccr8 This fixes several tests which snapshot remote windows under Fission. It also changes some other arbitrary tests that don't use remote windows, which I changed before I gave up on having an always-async API. Differential Revision:
