Fix thumbnail views not rotating w/ orientation

View has an optimization where it will not measure again if it
is exact and the measurement has not changed. This means that when an
onMeasure pass starts off for each task view on orientation change,
it does not get passed down to the view holding the thumbnail and
icon as its measure specs have not changed. This causes an issue as
we use this measure call to react to orientation changes and
re-measure the thumbnail view to match the orientation of the device.

To fix this, we call forceLayout on the child explicitly on orientation
change to ensure that we get the measure call. This sets the flag to
force a re-measure in the next layout.
