Assert that tests are run in the crate directory

Browse source 
To avoid regressions to the test runtime directory, this asserts that
all test types (unit, integration, doctest) are executed in the crate
(manifest) directory, no matter where that crate is in relation to the
workspace root.

See #8992 / #8993
