StyledText: fix reading of utf-8 documents

BNode::ReadAttrString does not check for the attribute to actually be a
string. It will return B_OK (and useless data) if called on a
B_INT32_TYPE attribute. Check the attribute type before reading.

Also remove various debug ouput leftovers.

May fix #12976.
