tests: optimize test-copytrace-heuristics.t
test-copytrace-heuristics.t tests the heuristics algorithm of copytracing. The
test has a pattern of making a server repo first and then cloning into a local
repo for each test to have public and draft commits. This is done because if we
have all draft commits and we have very less commits, heuristics will fallback
to full copytracing as that will be fast.
To avoid creating the server repo, we set the commit limit to -1 so that
everytime we perform the heuristics algorithm even when having full drafts and
tweak the config setting when we need to test the ability to fallback to full
copytracing.
This optimizes this test by 3 seconds.
