Issue Summary

When spaces are imported from server either by XML import or via CCMA, the attachments are referenced to respect space key <ri:page ri:space-key="SPACEKY_KEY" when these mages are moved in BULK the attachments are broken because they still keep referencing to old space.

Steps to Reproduce

1. Import or migrate a space from DC to cloud with pages that have attachments. 
2. Import on New spaces. 
3. after import, move the imported pages to another space as required. 
4. Delete the new space that was create on cloud during the import or migrations.
5. the attachments on the moves pages fail to load with error "UNKNOWN ATTACHMENTS" 

Expected Results

• Attachments should load on moved pages.

Actual Results

• The migrated or imported pages have attachments referencing the imported space key as follows <ri:page ri:space-key="SPACEKY_KEY"

• Because of this, when pages move to another space, they still reference the old migrated space. If the migrated space is deleted, images on the moved pages fail to load.

Workaround

Instead of moving pages from migrated space, Duplicate the pages.
