To also verify existence of the slots

Also some Prettier changes. Not sure why prettier-all-save
didn’t fix them in the previous commit.

Due date and Weight is EE only features.
We simply cannot move them to ce/vue_shared.
The only way to preserve current functionality while
making the component reusable is using a slot.

We are building related MRs feature and it will have the same
look and feel with related issues widget.
However, related issues is a EE only feature but related MRs is not.
That’s why, to be able to reuse existing components,
I move them to ce/vue_shared and updated references.
