Relations: Do not load nice path if "fullpath" is not a visible field

[BlackbitDevs]

Steps to reproduce bug (it is not really a bug but waste of resources / performance):

1. Create data object class with a many-to-many object relation,

• set a Path formatter,
• as Allowed classes select the class itself,
• select key as the only visible field,
• keep Enable Async Load in Admin disabled

2. Create an object of this class
3. Assign the object itself to the relation field
4. Reload object

In network panel you will see a request for get-nice-path which will return the nice path from the path formatter. But this value does not get displayed anywhere (because fullpath is not configured as a visible field).

This PR adds a check if fullpath is actually configured as a visible field and if not, the nice path does not get requested.
