Fix unable to change language

In some cases, recycler view receives the cancel touch event,
it causes recycler view doesn't update the new locale list.

Currently, we also treat cancel event as a signal to update the locale.
According to the document, we can treat cancel event as a up
event, but not perform any action that you normally would.

It's ok in our case since we check if updated list is same as
last one in adapater.

Test: Drag and drop locale item, and make sure the language system
is updated.
