Apex Test Runner ignores .forceignore (i.e. tries to run non-existent tests)

[brianmfear]

Summary

VS Code's Apex Test Runner does not appear to support .forceignore. This makes it impossible to run all tests if you have test classes that you've ignored. I specifically came across this problem while trying to create a repo where some of the work is pulled from a separate repo as a submodule; I cannot remove those .forceignore files from the source path without affecting other work in progress.

Steps To Reproduce:

1. Create a new project.
2. Add **/archived/** to the .forceignore file.
3. Create two folders in force-app/main/default/classes, active and archived.
4. Place a unit test class in each of these two folders. Only 1 should deploy, as archived is ignored.
5. Clicking the refresh button shows both classes.
6. Clicking the Run All button displays error.

Expected result

All non-ignored files should have their unit tests run. Alternatively, Apex Test Runner should just use the RunLocalTests command instead of RunSpecifiedTests.

Actual result

Error in output console: "This class name's value is invalid: XYZ. Provide the name of an Apex class that has test methods."

we resolved this a different way: you can only run tests that are in the org, so only those show up in the test panel
