AppWindowApiTest.Properties: Elim flakiness

This test was assuming that calling minimize() and maximize() followed
by restore() without waiting for onMinimized or onMaximized would
trigger onRestored. This is not the case on Mash, and is also a likely
cause of flake on other platforms.

[813/815] AppWindowApiTest.OnMinimizedEvent (TIMED OUT)

Looks like there are other reasons why this times out on Mac 10.10, I will re-disable this test there in addition to Linux.

See also issue 660582 for Mac 10.10, i.e. it may be failing there for other reasons.

Thanks Steven!
