List group collaborations AND List pending collaborations - Collaboration response is missing order property

## Description of the issue
It seems to be returning a collaborations resource in the response but the order property is missing from the collaborations resource.

## Current content
`
array(4) {
'total_count' =>
int(0)
'entries' =>
array(0) {
}
'offset' =>
int(0)
'limit' =>
int(100)
}
`

## Expected content
Collaborations properties should include:
- entries
- limit
- offset
- order (object)
- total_count
