Correct bug with items without attributes in wxGTK wxDVC.

Browse Source 
After the change to the sample in r62390 it turned out that wxGTK version
didn't handle items without attributes in a column where other items did have
attributes neither -- they inherited the last used attribute.

Fix this by remembering whether we are using any non-default attributes or not
and resetting them if we do.
