tdf#128046: preserve list levels on paste

done in two steps:
1) bullet and numbering properties must be included in the property
list of SvxUnoText on import from ODF clipboard (SvxReadXML)
2) in ConnectParagraphs, don't merge para attributes if the paragraph
to be deleted is empty. Paragraph breaks are inserted before paste so
this would make the last list level of the pasted text take the properties
of the empty paragraph and thus lose its indentation

Also updated tdf#103083 unit test to be more specific and test that
bullet properties don't get lost after paste. Previously only count
of SfxItems was tested which is somehow fragile and fails bc paste
adds a paragraph style
