Fix a bug about missing onConfigurationChanged

The original logic sends the new configuration to the non-activity
components only if there is any public field changed. However, it
doesn't use the latest configuration to compare to the current one,
which caused ActivityThread dropping some onConfigurationChanged
callbacks.

This CL uses the latest configuration to compare to the current one.
