commit: propagate --secret option to subrepos (issue4182)

Before this patch, `hg commit --secret` was not getting propagated
correctly, and subrepos were not getting the commit in the secret
phase. The problem is that subrepos get their ui from the base repo's
baseui object and ignore the ui object passed on to them. This sets
and restores both ui objects with the appropriate option.
