repo: look up nullrev context by revnum, not symbolic name

I think lookup of the 'null' symbol should be done via
scmutil.revsymbol() and repo['null'] is only supported for historical
reasons. However, repo[nullrev] is fine, so we can switch to that
instead of switching to scmutil.revsymbol('null').
