Show modal when claiming a reward

[dan1d]

This fixes PART of the issues reported in #1436
As @tzarebczan reported, this error Uncaught (in promise) Error: Actions may not have an undefined "type" property. Have you misspelled a constant?, the constant ACTIONS.OPEN_MODALS is not defined anymore and it throws that error as the type for an action when dispatching it is undefined:

dispatch({
          type: ACTIONS.OPEN_MODAL,
          data: { modal: MODALS.FIRST_REWARD },
        });

Seems like the code to open modals have been refactored and changed to notifications, as far as I understand.

Awesome! Can you update this to use lbry-redux? I just merged your other PR

@seanyesmunt Done!, I've also added another modal call to use notifications that was not working before!.
