Visualize ownership and lifetimes in tests.

[gerard-ryan-immersaview]

What is the problem you're trying to solve

Currently, the lifetimes do not show for #[test] functions or #[cfg(test)] modules.

Describe the solution you'd like

test code work the same as non test code.

Additional context

As a workaround, commenting out #[test] and #[cfg(test)] works.

[cordx56]

RustOwl uses compile result of workspace by using cargo check.
So if you would like to check #[cfg(...)], the cfg should be ON.
Currently, we cannot specify these options.
