\IncomingRequest method getFiles() - Should really return only arrays?

[nowackipawel]

if yes im wondering if can return empty array if there is no elements inside $_FILES instead of null

I'd like to propose for line 492:
return is_array($this->files->all())?$this->files->all():[];

After some investigation better place to make changes I think is populateFiles method of
class FileCollection.

To fix another issue earlier today, the returned value is now the FileCollection itself, which has some additional tools to work with.
