There was a panic! when the command `cargo update` was
executed in a workspace like this:
mkdir ws
cd ws
echo '[workspace]' > Cargo.toml
cargo new p1
cargo new p2
cargo update
The problem is that cargo tries to generate the Cargo.lock file
even if there aren't any members on the workspace.
This fix checks the existence of members in the workspace before trying
to do anything so at least we report an error instead of throwing a
panic!
