Description

Steps to Reproduce:

I was trying to complete System.Collections.Generics.List, but I got the non-generic version of this type:

TypeCompletionForGenerics

Expected Behavior: List<T> to be committed.

Actual Behavior: List was committed.

Contributor guide

Research direction
Investigate the completion logic for generic types in the 'Show items from unimported namespaces' feature. Focus on how the completion provider selects the correct type (generic vs non generic) when committing.
