sparse: don't enable on clone if it was a narrow clone When both sparse and narrow extensions are enabled and we do a narrow clone, sparse enables itself because it reads --include flag and thinks that user is trying to do a sparse clone. This patch changes that behavior, and now if both extensions are enabled and user passes `--narrow`, then the includes and excludes won't be considered as part of sparse profile.

tests: add tests for narrow clone when both sparse and narrow are enabled This patch adds tests for doing a narrow clone when client has both sparse and narrow enabled. As shown by this patch, we can see that the narrow clone has sparse enabled which we does not want here. Upcoming patch will fix this. Also while writing tests, I realized we don't have a flag to list the current sparse profile. Differential Revision: https://phab.mercurial-scm.org/D5478
