Iterate over Hash by key and value
Iterate over Hash by key and value

Sometimes, when running this, we were getting errors like:
  undefined method `last' for "645976":String (NoMethodError)

I'm not entirely sure why this is breaking in some circumstances and not
others, but in general it's going to be better to iterate over a Hash
explicitly by a key/value combo than a pair on which we call `.first` or
`.last`
