Fix Org Import duplicate collections (#5200)

This fixes an issue with collections be duplicated same as was an issue with folders.
Also made some optimizations by using HashSet where possible and device the Vec/Hash capacity.
And instead of passing objects only use the UUID which was the only value we needed.

Also found an issue with importing a personal export via the Org import where folders are used.
Since Org's do not use folder we needed to clear those out, same as Bitwarden does.

Fixes #5193
