Fix wxLogChain (and wxLogWindow deriving from it) broken by wxLog changes.

wxLogChain::DoLogRecord() only called DoLogRecord() on the old logger but not
the new one when the new logger was the same object as wxLogChain itself as is
always the case for wxLogWindow. The result was that nothing was logged into
the window.
