Fix the bubbles max height CtsVerifier test

The max window metrics will not return insets so in cases
where 2 or 3 button nav is turned on then the test could
fail incorrectly.

The normal window metrics in the bubble'd activity also
does not return insets so I need to pass them through.

Test: build CtsVerifier app and run through bubble tests
