logcmdutil: also check for copies in null revision and working copy

It's safe (and fast) to look for copies in the null revision, and it's
incorrect not to look for them in the working copy, so let's look in
both places.

Differential Revision: https://phab.mercurial-scm.org/D6544

Set up

  $ hg init repo
  $ cd repo

Try to import an empty patch

  $ hg import --no-commit - <<EOF
  > EOF
  applying patch from stdin
  abort: stdin: no diffs found
  [255]

No dirstate backups are left behind

  $ ls .hg/dirstate* | sort
  .hg/dirstate
