Cannot View the Source Code Definitions of csproj ProjectReference Include

Type: Bug

## Issue Description ##
Debugger is always referencing local ProjectReference included project from a metadata file created at [drive]:/Users/[user]/AppData/Local/Temp/MetadataAsSource/[guid]/DecompilationMetadataAsSourceFileProvider/[guid]/[file].

## Steps to Reproduce ##
First symptoms:
1) Add local project to anoter csproj using a ProjectReference tag.
2) Add code that references function from included project.
3) While using debugger, attempt to step into a function from included local project.
4) Result: Code is always stepped over.

Second symptoms:
1) Add local project to anoter csproj using a ProjectReference tag.
2) Add code that references function from included project.
3) Right-click > "Go to Definition" on function from included project.
4) Result: Navigates to MetadataAsSource file as mentioned in the the description of this issue.

## Expected Behavior ##
Allow viewing of included project code from original included location, rather than using decompiled MetadataAsSource files.

The expected functionality works on version 1.26.0 of the C# extension for vscode.

This issue appears to have started as early as version 2.0.328 available from the vscode extension marketplace.

Version 2.0.320 showed a different issue where the definitions of the included file could not be found when going to Right-click > "Go to Definition", so this new issue may be related to that issue where it is now creating the MetadataAsSource files so that the definitions can be found, but that does not fix the true issue here of not being able to locate the definitions from the original ProjectReference included file path.

## Actual Behavior ##
See section "Steps to Reproduce".
