hgweb: simplify the handling of empty repo

This abstraction have two advantages:

- If the revlog is empty, None of the code bellow is relevant,
  early returns seems a win.

- Abtraction of the 'emptiness' check will help later when we stop relying on
  nodefunc.

A bonus, with filtering, a non-empty revlog may not have '0' revision
accessible. It'll be easier to handle with the emptiness test in a dedicated
function

  $ echo "[extensions]" >> $HGRCPATH
  $ echo "mq=" >> $HGRCPATH

  $ hg init

  $ echo 'base' > base
  $ hg ci -Ambase
  adding base

  $ hg qnew -mmqbase mqbase

  $ hg qsave
  $ hg qrestore 2
  restoring status: hg patches saved state
