Fixes #4964

Ordered the images by timestamp when they come from external sources (share button)

I think someone else is assigned to this mentioned issue. Is it @nicolas-raoul ?

@JesusMurguia Can you please ask at #4964 to be assigned? With GitHub I can technically not assign you unless you comment on the issue. Thanks!

I just tried and strangely the pictures are presented in the opposite of the historical order: Last to first. Was it working in your tests? Maybe the order gets mixed up later? Or maybe just inverse the order? Or maybe file timestamp are not reliable and we should instead rely on EXIF dates?

By the way thanks for switching to Timber, that's perfect!

Yeah, I just left the order in the opposite way because I was testing both directions. I changed it to the right order now, my bad!

I took 4 pictures of a clock with the seconds on 1, 2 , 3, 4 in order.

With this pull request, when selecting the 4 pictures with the normal picker they are not in order. Same with custom picker. Any idea why?

[JesusMurguia]

The changes only affect the images coming from external sources like the share button on the gallery, because these images don't respect the selection order, when using the normal and custom picker from inside the app, the images are sorted by selection order, I did it this way because the issue was referring specifically to this uploading method.
