hgweb: explictly pass basectx in webutil.diffs
There's only one case where `basectx` parameter is None (over two usages), so
it's probably not worth handling the special case as it makes code-reading
harder.
Along the way, use ctx.p1() instead of checking for ctx.parents() being empty
which should not occur.
