rust-analyzer.cargo.features can break running of tests in workspaces

[jplatte]

In a workspace with multiple crates, where some have a feature of a certain name but others don't, you may want to set "rust-analyzer.cargo.features": ["feature-name"] to have feature-gated code benefit from rust-analyzer's functionality.

However, with that setting, when trying to use RA's "Run test" helper on a test inside a crate without a feature named feature-name, RA still passes --feature feature-name to Cargo, leading to an error because that feature doesn't exist.

Bump, this has been a huge pain point for me, would love to see this fixed.
