Remove two unneeded asserts. Both checked a condition that is commonly encountered and which
is not dangerous or harmful.

* LayoutTests/platform/mac-wk2/TestExpectations: Unskip test.

* Source/WebCore/rendering/RenderVTTCue.cpp:
(WebCore::RenderVTTCue::repositionCueSnapToLinesSet): Remove assert.
(WebCore::RenderVTTCue::repositionGenericCue): Ditto.
