Fix collaboration getInfo() method
Fix collaboration getInfo() method

getInfo() should be making a call to /collaborations/{id} if it's
retrieving information about a collaboration. Old method was making a
call to /collaborations resulting in a 400 error as the endpoint
/collaborations does not accept a GET without a collaboration id or
?status=pending
