Redirect Admin power button on click to admin users

[WIP]
not sure why you're checking for nil, maybe you should make those values required, anyway, you could use something like
```
def award_title(award)
   badge.award.try(:title)
end
```

or, as far as I can see, why don't you delegate the title to award from badge?
```
delegate :title, to: :award, prefix: true, allow_nil: true
```
