tests: divorce blackbox test from test-dispatch.py

I used test-dispatch.py to demonstrate what would happen if
a log file changed from being readonly to writable, by
having it replace a directory (proxy for readonly/not-writable)
with a log file in between transactions of a running python
process (proxy for Mercurial).

This commit makes it easier for people to follow what the test
is doing, by creating a real file that people can read.
