logcmdutil: use the same data as {file*} template keywords (issue6642) Since 0c72eddb4be5 template keywords that show files use a different source of data than ctx.p1().status(ctx). These two functions in logcmdutil also show file lists when needed (e.g. log with --debug flag), but previously they used the old way of just looking at status compared to p1 and it resulted in differences between e.g. hg log --debug and hg log -T '{file*}'. test-phases.t needs an adjustment because 7 is a merge commit of two topological branches and one of them introduces files C, D and E.
