rust-code-analysis-cli -m -p . at workspace root shows nothing

[jayvdb]

I am using https://github.com/mozilla/rust-code-analysis/pull/1086 , but it is working when I using -p path/to/member/src/lib.rs, and -p path/to/member/

However when I use -p . at the workspace root where top level Cargo.toml contains only workspace members and no package in the top level Cargo.toml.
