Call View#setHasTransientState in TextView#spanChange.

setHasTransientState(true) and setHasTransientState(false) have to
be coupled, but they were not always coupled in TextView. e.g. when
we fire PROCESS_TEXT intent.
With this CL, TextView calls setHasTransientState() always when
selection is created or cleared to make sure 2 setHasTransientState
calls are always coupled.
