[SPIKE] Fix typing on Android

[whatthewhat]

This is not a proper fix for https://github.com/bustle/mobiledoc-kit/issues/589, but rather a hacky workaround for anyone that really needs some kind of Android support. It does however work on my Pixel and in the emulator without breaking existing use cases. I'll keep this branch alive until a better fix is implemented.

After spending a bit of time reading code I'm still not familiar enough with Mobiledoc internals to attempt a proper fix.. @mixonic I wonder if your attempts to operate without keypress (1, 2) were sucessfull? That approach could probably fix the spellcheck issue (https://github.com/bustle/mobiledoc-kit/issues/621) as well by eliminating rerenders?
