bug(android): double-tap on Shift inconsistent

When in caps layer and double tapping on the Shift button the keyboard should toggle between shift layer and caps layer. However, it's possible to end up in the default layer instead. See the very end of the attached screencast. You might have to single step through the frames to see that there are two taps. What's interesting is that when single stepping over that last double tap you can see that it changes _shift layer → caps layer → default layer._ For the correctly working double taps it's _shift layer → default layer → caps layer_.
