Fix GridFSLoader

[aldeck]

It seems that a previously suggested patch never made it into the repo (cf. issue #305)

[peterrehm]

Can you merge this one? It is the same as in #331 and is not working. It would be great if you could tag a new minor release as well.

There were several commits that reverts previous work. Let's say one commit changes $image['file'] -> $image->getFile() where the next one changes it back. I am not sure why different people have such problems. Maybe because of the grid fs version they use.

I think both variants has to be supported.

What we could do is to check if $image['file'] exists and if not use the getter. I dont see why there should be access as array possible....

According to the history it was fixed in 0.x. https://github.com/liip/LiipImagineBundle/commits/0.x/Imagine/Data/Loader/GridFSLoader.php

But 1.x somehow misses this change: https://github.com/liip/LiipImagineBundle/blob/master/Binary/Loader/GridFSLoader.php

I think we can merge this as is

Awesome, thanks 👍

Thanks guys :-)
I guess the array access was working with a very early version of the doctrine/mongo odm.
