Can't follow error in Problems tab in C++ project under WSL (re-open #2786)

WSL 1

Steps to Reproduce:

1. Open pure makefile project in VSC under WSL, e.g. Ubuntu 16.04 with gcc and make.
2. Configure tasks.json for compilation (see below).
3. Create error. E.g. int a = "a";
4. Compile project using task.
5. Switch to PROBLEMS tab and click on error message.
6. Popup message will inform that:

Unable to open 'file.cpp': Unable to read file 'vscode-remote://wsl+ubuntu-16.04/file.cpp' (Error: Unable to resolve non-existing file 'vscode-remote://wsl+ubuntu-16.04/file.cpp').

tasks.json:
{ "version": "2.0.0", "tasks": [ { "label": "Make project", "type": "shell", "command": "make", // use options.cwd property if the Makefile is not in the project root ${workspaceRoot} dir "options": { "cwd": "${workspaceRoot}" }, // start the build without prompting for task selection, use "group": "build" otherwise "group": { "kind": "build", "isDefault": true }, "presentation": { "echo": true, "reveal": "always", "focus": false, "panel": "shared" }, // arg passing example: in this case is executed make QUIET=0 "args": [ "QUIET=0" ], // Use the standard less compilation problem matcher. "problemMatcher": { "owner": "cpp", "fileLocation": [ "absolute" ], "pattern": { "regexp": "^(.*):(\\d+):(\\d+):\\s+(warning|error):\\s+(.*)$", "file": 1, "line": 2, "column": 3, "severity": 4, "message": 5 } } } ] }

Same issue if change problemMatcher to "fileLocation": "relative",.

Attaching test project. Open it in WSL and hit Start Debugging in Run tab
test.tar.gz

Does this issue occur when you try this locally?: No
Does this issue occur when you try this locally and all extensions are disabled?: Without extension - Yes, this is not C++ extension issue. Locally - no, this is WSL1 issue.

Start with the attached test project in WSL 1 and reproduce the failure by running the configured make task, then selecting the error in the Problems tab. Compare the absolute and relative problemMatcher configurations and trace the vscode-remote URI resolution. Done means selecting the reported error opens the C++ file instead of showing a non-existing-file error.
