You can't start or clear loads in RequestListener or Target callbacks

Hi, thanks for this awesome library.

In my simple app, if i switch between tabs very fastly, the app crashs leaving this:

                                                                Process: co.my.araa, PID: 23545
                                                                java.lang.IllegalStateException: You can't start or clear loads in RequestListener or Target callbacks. If you must do so, consider posting your into() or clear() calls to the main thread using a Handler instead.
