Fix recycler and empty view hide/show logic 

The `emptyViewHandler` already handles hiding and showing both the empty
view and the recycler view on data changes, so this commit removes this
part of the logic from the episodes fragment.

It also hides the empty view right after creating the recycle adapter
for the first time (when the fragment is created) to prevent the
progress bar and the empty view from being displayed at the same time.

`createRecycleAdapter()` signature was changed to make it explicit that
it depends on both the `recyclerView` and `emptyViewHandler`. Similarly,
`onFragmentLoaded()`, since it also depends on the new data that gets
loaded.
