VS extension complains about non-existing values

[Pouriya-Inmanta]

Description

While modifying and refactoring models, the extension keeps reporting old values that are either removed or renamed as missing.
This behavior is more apparent when dealing with the indices and refinements of a model.

An example would be this picture :

Here, the extension is complaining about a non-existing refinement, ntppeertypeYang which is replaced by ntpPeerTypeV4Yang in the second line.

After editing some other parts of the model, eventually, the error vanishes.

One more point to add, the error vanishes when a newer error comes to light.
