When accessing raw['workspace'] internally via from_raw, a KeyError is raised.

[dabao1990]

Describe the bug
This error occurs because you cannot directly issue commands in this way, right?

To Reproduce

python3 run_unittests.py -v -k "test_update_dependency"
Meson build system 1.12.0 Unit Tests
pytest not found, using unittest instead
test_update_dependency (unittests.cargotests.CargoTomlTest) ... ERROR

It works here, all of

• python -m pytest -v -k "test_update_dependency"
• ./run_unittests.py -v test_update_dependency

while ./run_unittests.py -v -k test_update_dependency does not work but with a different error that seems unrelated:

Meson build system 1.12.99 Unit Tests
pytest-xdist not found, tests will not be distributed across CPU cores
ERROR: usage: python3 -m pytest [options] [file_or_dir] [file_or_dir] [...]
python3 -m pytest: error: argument -k: expected one argument

Can you reproduce with the other two commands?
