[Patch] Wiki to HTML rendering of Description, and more robustness for Description and Comment rendering

[pipern]

If the change comment for a ticket include hyperlinks, then it failed with this exception:

...
  File "...trac/wiki/formatter.py", line 1147, in handle_match
    return internal_handler(match, fullmatch)
  File "...trac/wiki/formatter.py", line 529, in _shref_formatter
    return self._make_link(ns, target, match, match, fullmatch)
  File "...trac/wiki/formatter.py", line 590, in _make_link
    return self._make_ext_link(ns+':'+target, label)
  File "...trac/wiki/formatter.py", line 653, in _make_ext_link
    (self.req or self.env).abs_href.base
AttributeError: 'str' object has no attribute 'base'

because we were passing in a string for abs_href to Mock req. I've changed that to pass in the real env.abs_href, and also started to render the Description as HTML too.

Patch attached.

Patch to render description and use env.abs_href in the Mock req rather than string returned by env.abs_ref()

The first seems to have gone with your patch. Thank you!
It occurs when adding an attachment to a ticket without writing a description.
The second error persits. Perhaps I will open a new ticket for it.

Fixes #7250 Thanks pipern!

Tested attachment with no description and it works fine in trunk.
