Hi

When I currently use the prerelease rust-analyzer VsCode extension (v0.4.2025) I'm not able anymore to debug indivitual tests via the 'debug link' above the test.

it fails with

    Finished `test` profile [unoptimized + debuginfo] target(s) in 0.00s
     Running unittests src/lib.rs (target/debug/deps/vs_debug_issue-c35e030d2028369f)
error: Unrecognized option: 'message-format'
error: test failed, to rerun pass `-p vs-debug-issue --lib`

With the release version (v0.3.2020) it still works.

I think I tracked it down to the change in this PR as it adds -- into the arguments list that is passed to the find the test artifact while later (in toolchian.ts --message-format=json is added to the end of the arguments list.

So currently on master the argument list looks like the following which has the --message-format=json after the -- and in my view causes the issue as it is now passed to the test executable instead of to cargo:

while running the release tag v0.3.2020 the argument list looks like

Confirming, the issue is happening in the wild and there are very few hits on Google yet.

To clarify (TL;DR): the current workaround is to downgrade rust-analyser in VsCode to Release version via extension menu
