Load the bugdoc, the format redline at the doc end has the Quote char
style, reverting the redline should result in the Strong char style, but
results in no character style.
What happens is that XMLChangedRegionImportContext::SetChangeInfo()
assumed that the style name of the format redline is always an automatic
style, while it may be a named character style, too.
Fix the problem by splitting the style name into two parts in
XMLChangedRegionImportContext::SetChangeInfo() (named style, automatic
style) and then work with that pair in
XMLRedlineImportHelper::InsertIntoDocument(), similar to how
XMLTextImportHelper::SetStyleAndAttrs() works for <text:span>'s style
name.
The ODF export worked already.
