Delegates highlighting after voting is broken

[slaweet]

Expected behaviour

After a vote is placed, voted delegates should be gray.
After the transaction is confirmed all delegates should go back to normal

Actual behaviour

After a vote is placed, one of these two issues happen

• if delegate was selected by the checkbox in the table, then it stays gray forever.
• if delegate was selected in the typeahead component in the vote modal dialog, then it doesn't go gray at all.
