Fixed a regression where we incorrectly reported that the dialpad was visible.

A request was made to update the value of #isDialpadVisible, in the process a
regression was introduced that would cause #isDialpadVisible to return true
when the dialpad's root view was null. This caused a NPE when we tried to
animate it.

We should now return the correct value in the scenarios important to our
partners as well our users and animations.
