sw_redlinehide: replace bogus implementation of SwPaM::InvalidatePaM()

Sending SwInsText will mess up merged paragraphs. Instead, send
SwUpdateAttr with which-id 0, which results in InvalidateRange_() being
called with at least 1 character.

This appears to be called only by fieldmark UI, and now asserts in
UITest_writer_tests5 DateFormFieldPropertiesDialog.dateFormFieldDialog.test_date_field_with_custom_format
