Update ink overflow test when applying outline

The test is to check |NeedsLayout| when outline is applied,
but the current test may set |NeedsLayout| because it changes
a culled inline box to a non-culled inline box.

This patch changes the test to make sure the inline box is
not culled before applying the outline.

This patch does not fix the issue, but makes sure to change
the test result when we fix this problem for outline.
