[BUG] ccui.EditBox - Black Label When Editing Finished

Version: cocos2d-x-3.7 Lua

Platform: android

Issue: When editing finish, label turns to black box.

After checking logcat, found that editBoxCallbackFunc (in file UIEditBoxImpl-android.cpp) used to refresh the text of the EditBox were invoked in different thread, neither in GL thread nor in UI thread when editing finished occasionally.
