Remove unused imports and rearrange some imports.
This was mostly done automatically.
I really don't know if this belongs here, maybe there is a reason to keep them around that I am not seeing here. On my previous PR the IDE showed me a lot of unused imports which confused me and it desperately wanted to remove them, so I thought it might be better to do all of them in a separate PR.
