tree-wide: Remove stacktraces from tests testing throwing clones (#18748)

This is in preparation for the possible future transformation of `clone` into a
function call, but also meaningful on its own, since the purpose of the tests
is not to test the stack trace generation, but rather that an exception was
thrown. It also cleans up some unreachable code in the tests.
