Baseline tests: improve focus setting and clearingHEADdev

Set focus on the test window so that the tested widget doesn't have it.
Remove the "PublicWidget" hack, we have public QWidget APIs to find the
next widget in the focus chain that we can use to transfer focus
reliably. Use TabFocusReason to maintain existing behavior, and to
test that widgets that handle that specifically appear correctly. Clear
the focus on the test widget by setting it back to the window after
taking the "focused" snapshot.

Add QCOMPARE and QVERIFY to assert that the test is in the right state
before taking screenshots.
