rm_work removes artifacts required by wic. Wic will complain that rootfs
can't be found. There is a bug about i https://bugzilla.yoctoproject.org/show_bug.cgi?id=7042
I closed it as not a bug as wic uses build artifacts by design.

I don't fully understand command line options in your example, but generally you're right.
wic will take image name from -e option and run "bitbake test-image" in this case.
