I'll revert this change, its my IDE which sorts the imports in alphabetical order

I'm fine with that rule by the way, I would just like it to be documented somewhere (and maybe enforced).

https://github.com/slevomat/coding-standard/blob/master/doc/namespaces.md#slevomatcodingstandardnamespacesalphabeticallysorteduses-
In order to enforce it, we'd need to add a git submodule for the slevomat standard (which we planned to do anyway) and enable that particular sniff. (and fix it everywhere first)

Leaving this in the review will be in step closer to fixing it everywhere (;
