V14: Fix sorting by "creator" on collection view

[elit0451]

Details

• Allows for items in a collection view to be sortable by "creator", aka "Created by" field;
  • Changing the order of transforming "creator" to "owner" since we are performing a check against the collection view properties and there it is named "creator" => we need to do the check first.

Test

• Create a root doc type with collection view enabled & a child doc type;
• Create some content to be able to sort items in the collection view;
  • Use at least 2 users when creating the content items, so that you can see a difference when sorting.
• Modify the "Columns Displayed" on the "List View - Content" data type to have the "Created by" property - you can find it under "Document type" > the child doc type > "Created by"
• In the Content section, navigate to the Collection app;
• Verify that by clicking on the "Created by", the items get sorted.

Theres a front end bug preventing us from getting out collection view's at the moment, will test this out ASAP when that is fixed 😁
