Automatically upgrade debugging experience (single process, no thread
pool) when:

1. we only run a single test
2. user specifies `-j1`

Fix `--max-failures` in single process mode. Option did not have an
effect in single process mode.

Add display feedback for single process mode. Adapted test.

Improve argument checking (require positive integers).

`--single-process` is now essentially an alias for `-j1`. Should we
remove it?
