templatekw: compare target context and its parent exactly (issue4690)

Before this patch, template keywords `{file_mods}`, `{file_adds}` and
`{file_dels}` use values gotten by `repo.status(ctx.p1().node(),
ctx.node())`.

But this doesn't work as expected if `ctx` is `memctx` or
`workingcommitctx`. Typical case of templating with these contexts is
customization of the text shown in the commit message editor by
`[committemplate]` configuration.

In this case, `ctx.node()` returns None and it causes comparison
between `ctx.p1()` and `workingctx`. `workingctx` lists up all changed
files in the working directory even at selective committing.

BTW, `{files}` uses `ctx.files()` and it works as expected.

To compare target context and its parent exactly, this patch passes
`ctx.p1()` and `ctx` without `node()`-nize. This avoids unexpected
comparison with `workingctx`.

This patch uses a little redundant template configurations in
`test-commit.t`, but they are needed to avoid regression around
problems fixed by a4958cdb2202 and 1e6fb8db666e: accessing on `ctx`
may break `ctx._status` field.
