Type system editor: uid field types cannot be references to other type names

[danielmai]

Steps to reproduce

1. In Bulk Edit (or outside of Ratel), create the following schema with a type field that refers to a different type

refersTo: [uid] .
type TypeA {
  refersTo: [TypeB]
}

The type definition shows that refersTo is of type [TypeB]

When clicking on Edit Type, the predicate name along with its actual type is shown

After clicking Save, the field type turns into [uid]

Expected result:

The type definition should retain the information that refersTo references TypeB nodes.

A related issue is, as implied by Step 1, we can't create types in the UI that refer to other types by name.

Will be fixed with #123

Fixed, and type system is going to be typeless soon, so probably not needed anymore
