[TTS] Fix flaky second-tap on tap-selection.

[TTS] Fix flaky second-tap on tap-selection.

When a Tap selection is present, a second tap shows the pins, and
the Bar should keep showing.  However this seems to currently be
flaky.

This CL adds a check when a Tap is recognized to see if we're
already showing a Tap-selection.  We were incorrectly starting
a Tap sequence in response to this second tap but that's not
needed since we'll soon get a message for the Long-press gesture
when the pins show.
