rebase: use "commitforceeditor" instead of "ui.edit()" for "--collapse"
Before this patch, "rebase --collapse --edit" without "--message" and
"--logfile" invokes editor twice unexpectedly:
1. explicit "ui.edit()" invocation in rebase extension itself
2. indirect invocation in "localrepository.commit()" with "editor =
commitforceeditor" assigned by "--edit" option
This patch uses indirect "commitforceeditor" invocation instead of
"ui.edit()" for "--collapse" without "--message" and "--logfile" to:
- suppress redundant the former invocation
- ensure editor invocation even when "--edit" is not specified
