import of nonexistant module in macros.py

[Dmitri]

There is no html in trac.wiki (I cannot find it even in trac-0.10 branch) Drop this import as it probably doesn't used anywhere:

wikinegotiator/macros.py

(In [9266]) Do not import non-existant module (fix #7644). It is an old garbage and trac.util.html was the right one.
