Voter deletion fails

Deleting a voter from a polling group fails because the original line for accounts.getId() obtains a copy of the object in accounts rather an reference to it

     // Find the voter in the group
     GroupAccounts accounts = getTable<GroupAccounts>(group->id);
    auto account = accounts.getId(*voterId, "Unable to remove voter from polling group: voter name not recognized");

The subsequent attempt to erase that object from accounts ...

     // Delete the voter from the group
     accounts.erase(account);

... fails because the copy of the object is not in accounts.
