[Media Router] Handle header tooltip when no cast mode host exists.

[Media Router] Handle header tooltip when no cast mode host exists.

Currently, if the cast mode's host is null, the tooltip shows "null". Show no tooltip if the host is null. In non-sink list views, continue to show no tooltip (as expected).
