autotest: Make WM tests wait for initial browser window.
I suspect that at least some of the failures that have been
seen from the desktopui_WindowManager* tests may be caused
by the tests starting to do things before the initial
browser window has been mapped, and then the focus ending up
on the browser window when it finally shows up.
I'm also removing some Alt-Tab/Alt-Shift-Tab hotkey-sending
from desktopui_WindowManagerFocusNewWindows that seems to be
flaky. I haven't been able to figure out what's going on
here, but we already have a separate test that tests other
hotkeys, so this doesn't seem particularly useful to test.

TEST=ran the tests a few times and only saw "waiting for logout" failures that are presumably caused by the slow USB stick that I booted from
