Bug 22886: Missing space between fields from Keyword to MARC mapping in cataloguing search

If you have multiple subfields mapped to the 'subtitle' keyword,
those fields will show up without separating space.

To test:
- Add 3 subtitle entries in Keyword to MARC mapping for a framework
  - 245 b
  - 245 c
  - 245 h
- Edit a record, make sure the framework matches, add:
  - 245 b, c, h
- Search for it in cataloguing search (not catalog!)
- Verify the subtitle fields show, but are all concatenated
- Apply patch
- Search again and verify the display is improved with a separating
  space
