tests: avoid referring to pvec in demandimport test

Nothing else currently uses pvec, so we may want to delete it (but
Augie Fackler says he may want to use it). To enable deletion, this
patch replaces it by the error module in the demandimport test (any
module works). However, since the error module had already been loaded
at this point in the test (via the util module), I moved it earlier in
the test so it's still not loaded (although I'm not sure if that's
even relevant to the test).

Can not modify dirstate outside

  $ mkdir outside
  $ touch outside/f1
  $ hg debugwalk -I 'relglob:f1'
  matcher: <includematcher includes='(?:(?:|.*/)f1(?:/|$))'>
  f  inside/f1  inside/f1
  $ hg add outside/f1
  abort: cannot track 'outside/f1' - it is outside the narrow clone
  [255]
  $ touch outside/f3
  $ hg add outside/f3
  abort: cannot track 'outside/f3' - it is outside the narrow clone
  [255]

But adding a truly excluded file shouldn't count

  $ hg add outside/f3 -X outside/f3

  $ rm -r outside

Can modify dirstate inside

  $ echo modified > inside/f1
  $ touch inside/f3
  $ hg add inside/f3
  $ hg status
  M inside/f1
  A inside/f3
  $ hg revert -qC .
  $ rm inside/f3

Can commit changes inside. Leaves outside unchanged.

Some filesystems (notably FAT/exFAT only store timestamps with 2
seconds of precision, so by sleeping for 3 seconds, we can ensure that
the timestamps of files stored by dirstate will appear older than the
dirstate file, and therefore we'll be able to get stable output from
debugdirstate. If we don't do this, the test can be slightly flaky.
