module: handle Top-Level Await non-fulfills better

Handle situations in which the main `Promise` from a TLA module
is not fulfilled better:

- When not resolving the `Promise` at all, set a non-zero exit code
  (unless another one has been requested explicitly) to distinguish
  the result from a successful completion.
- When rejecting the `Promise`, always treat it like an uncaught
  exception. In particular, this also ensures a non-zero exit code.
