Subject: [PATCH] Android: Handle ImhNoTextHandles flag from InputMethodHints

[0]Qt::InputMethodHints has a flag ImhNoTextHandles that was not
handled. This flag should be considered when QAndroidInputContext is
updating Text handles position.
What is more, this flag can be used to fix the problem with visible
text cursor out of the text object.
