Resolves: fdo#51772 failure to import a specific .rtf file

In this example the xCharacterStyles->getByName(aCharStyle) throws, and the
whole import is abandoned

i.e.  xRet.set(xCharacterStyles->getByName(aCharStyle), uno::UNO_QUERY);

so to keep things simple wrap the entire block in a try catch and return
an empty xRet. Could use the hasByName around the specific failing query.
