Two versions of EventBus lib available in wpandroid

[hypest]

We currently expose 2 versions of EventBus in wpandroid:

• de.greenrobot.event:2.4.0
• org.greenrobot.eventbus: 3.0.0 (via FluxC)

There doesn't seem a good reason to have both around so, we should consolidate.

By quickly having a look at this it seems we will need to migrate the usage of registerSticky() which has been depricated in 3.x versions of the lib.
