This CL adds a very low risk because most (but not all) changes affect
only Launcher behavior during the test.
This should fix a lab-only flake when all apps keeps changing while
the test is working with it.
Example: test figures out which icon to click, by the moment it clicks
there, there is another icon there, or the icon is under the search box,
and clicking opens IME.
Switching test devices to airplane mode didn't help. The earlier change
that prevents popup menu cancellation is not general enough.
Now the tests are given an API to explicitly freeze and unfreeze
all-apps, which should be a final solution.

This time, Launcher doesn't send a completion event upon switching from
Home to all apps.

This eliminates an unreliable timeout.
Also removing an unnecessary check for harness that is done by the
called method.
