tests: replace `hg id --debug -i` command substitution with non-debug command
The censor and convert tests were failing on Windows because the `--debug` flag
also prints debug messages, and at least some of these were outputting:
skip updating dirstate: identity mismatch ${node}
Obviously that causes cascading problems. The other tests were OK, but it's
better to use a non debug command for stability.
