Removed now obsolete feature flag and tests.
Removed obsolete swipe refresh state from BookmarkFragmentState
Also adapted tests and remove obsolete ones.
Change the DiffUtil callback for bookmarks to use the generated equals()
method instead of only checking the title and url fields. This prevents
the BookmarkNode in our state from getting out of sync with the
BookmarkNode the viewholder is bound to.
Removed label from nav_graph that caused label to be set for each navigation
Removed title setting in onCreate() called for each navigation
Changed logic for checking current root when setting UI for normal mode
Show or hide overflow menu for entire list is triggered when mode is changed
For bookmarks, due to implementation of selection and diffUtil,
additional check is necessary for current item (last selected) that is redrawn
* For #4396 - Rename BookmarkInteractor methods
Following the naming model used in other Interactors this too will use reactive
method names in the form of "on..." instead of the previous imperative model.
Kept the imperative naming model for the methods from `SelectionInteractor` as
they are a new addition and I'm not sure about the future direction.
* For #4396 - Add a BookmarkController
It abstracts the Fragment behavior in a contract through which various
Interactors can inform about the specific View changes and can ask for
modifications in their container Fragment.
This contract and it's implementation - `DefaultBookmarkController` are the
result of extracting the container Fragment's business logic from
`BookmarkFragmentInteractor` in it's own standalone component.
* For #4396 - Refactored Bookmark related tests
Added a new `BookmarkControllerTest` tests class which complements the new
`BookmarkController` to ensure that it properly operates on `BookmarkFragment`
Also refactored the existing `BookmarkFragmentInteractorTest` to accommodate
`BookmarkFragmentInteractor`'s now more specialized behavior.
