Change redux store on success claiming

[anxolin]

Just small continuation of #2126

As promise, this one adds the mutation of the state.
If i new it would be so little, i wouldn't have done 2 PRs :)

Notes, as expected, the success window show 0 vCOW. I assume is because now it's consumed the opportunity. This should be fixed, but in another PR.

To Test

1. Same as Add claim finalized middleware #2126
2. Watch for that confeti

Code looks ok, but you are probably using the old contract, claiming windows are closed
