localrepo: extend "changeid in repo" to return True for workingctx revision

This is necessary to implement "wc" symbol for workingctx, that will be used
as follows:

    $ hg annotate -r wc FILE

In principle, "rev in repo" should be True if "repo[rev]" can return a context
object. But when it was implemented by ea3acaae25bb, lookup() had a long logic
to map all sorts of changeids to nodes, and "None in repo" did crash because
lookup() could not accept None. So I assume that the case of changeid=None was
not considered.

Now "None in repo" doesn't crash, it should be True for workingctx revision.

Behavior of "changeid in repo":

    revision    "null"  existing rev  None (workingctx)
    ----------  ------  ------------  -----------------
    original*   True    True          TypeError
    current     True    True          False
    this patch  True    True          True

    (*original: ea3acaae25bb)
