Remove dismiss keyboard logic

Turns out the popping a screen while keyboard is
open has no side effects. The issue was in fact
that under some condition, when adding a screen
back after it was previously removed caused the
screens constructor to be called.

This commits prevent startReactApplication from
being called by setting mAttachScheduled flag.
