String based parser: Sort and distinct does allow using public field name

[sync-by-unito]

The string query parser is not able to find fields by their public field name on sort and distinct operations:

No property 'mHungarian' found on object type 'class_with_policy' specified in 'sort'

• public name: "mHungarian"
• inner name: hungarian

#4555 fixed the issue except for one corner case, name aliasing does not work when using the public field name on backlinks of RealmResults.

@LinkingObjects("columnRealmLink")
final private RealmResults<AllTypes> columnRealmBackLink = null;

distinct(columnRealmLink) = works
distinct(columnRealmBackLink)= does not work
