display info on hover not working when ambiguous definition occurs

[AustinZhu]

Steps to reproduce this problem:

1. create a single .hs file
2. import some module and define a function whose name collides with a function in the module.
3. save the file and restart VS Code

In my case, it does highlight the error that ambiguous definition occurs, but it seems that the extension is not inspecting other parts of the code. When I hover on a function or a variable, it shows an empty small window instead of the definition.

This is to be expected, since we typecheck the project and provide hover information based on the type checking information. If you introduce an error now, we can use the information from the last successful typecheck for hover. If you close your session and open it from new, we don't have all the caches, so some features don't work

Thank you for the reply! It would be great if some improvement can be made to deal with this issue. I'm not sure if the typecheck infomation can be preserved or there is a way to circumvent naming conflicts when doing typecheck :).
