inhibit: move transaction wrapping outside of repo setup Before this patch, transaction wrapping code was done in reposetup. It happened to cause stackoverflows in repos with a lot of subreps. This patch moves the wrapping to extsetup and avoids this problem.

tests: ignores other core output in capability testing This will avoid breaking the test anytime core changes.

evolve: make uncommit respect allowunsable Before this patch, the uncommit command was performing the same way regardless of the value of experimental.evolution. With this patch if the configuration does not allow unstability, uncommit won't create instability.
