Remove unnecessary `Hash#to_a` call
Inspired by https://github.com/rails/rails/commit/931ee4186b877856b212b0085cd7bd7f6a4aea67
```ruby
def stat(num)
start = GC.stat(:total_allocated_object)
num.times { yield }
total_obj_count = GC.stat(:total_allocated_object) - start
puts "#{total_obj_count / num} allocations per call"
end
h = { 'x' => 'y' }
stat(100) { h. each { |pair| pair } }
stat(100) { h.to_a.each { |pair| pair } }
__END__
1 allocations per call
2 allocations per call
```
