Reordering of Tags makes snapshot impossible on CreateGIFVC

[daiku60]

In 635e70f, any time a snapshot test is run, the values of the tags are ordred differently. Propose a solution for that, so that the tags are always ordrered the same way

I would use this

self.tagView.addTags(Array(vm.tags).sorted(by: <))

in GIFDetailsViewController's configureFor method.

I like it, go ahead and propose a PR!
