Prevent thread assertion for HTC mail apk

Prevent thread assertion for HTC mail apk

HTC's mail apk calls evaluateJavaScript() inside
InputConnection#setComposingText(). This is problematic with ImeThread
feature since InputConnection methods are now running on its own thread
(IME thread). This causes a thread check assertion in Android's framework
(android.webkit.WebView).

As a workaround, we set sEnforceThreadChecking to false immediately after
it was set in WebView's constructor.

HTC is actively fixing their apk to avoid this crash, but as a last resort,
this workaround will help avoid such a crash.
