Describe the bug
Pinned items: When pasting Pinned items, they duplicate below the pinned area and then the duplicates are also pinned there and take up additional space.

To Reproduce
Start with a list that has pinned items at top and then paste them into a document by double clicking on a pinned item. This will put the pinned item in CopyQ below the pinned items area and then theses duplicate pinned items are now themselves pinned in this new area and take up addiotnal space.

Expected behavior
Any duplicate pinned items should not be pinned again and should be treated like any other copied item, ie not pinned again.
