aura: Fix input method and a11y status area browser tests.

This fixes InputMethodMenuButtonTest and
AccessibilityMenuButtonTest, which were failing due to the
same NULL-status-area problem as the tests fixed by r110851
and r111006.

BUG=103482,103492
TEST=ran them for both aura and non-aura chrome os
