Subject: [PATCH] Support setText in RCTTextInput

Summary:
Examples that use defaultValue as part of their declaration (such as
those examples under UIExplorerApp's TextInput) were being ignored. This patch
supports having text set directly on RCTTextInput and handles it properly.
Note that this patch depends on D2962643 and D2964847, without which the
TextInput example will look wrong.

Differential Revision: D2968002
