All versions of Keen (Experimental WebApp Wrapper)

* Fixes a bug that caused the app to crash in about 1% of cases (base issue: https://github.com/GoogleChrome/android-browser-helper/issues/89). Note still opens up as a white screen on some devices, and on others has sign-in issues :( If it doesn't work, you can use Keen directly from the website too: https://staykeen.com
