tdf#119294: reimplement fix for tdf#118859

When removing paragraphs with mail mere fields, both field type reference
and node reference could get invalid, because field type will be destroyed
when its last field is gone; and node will be destroyed if it is in a fly
with anchor in another node which gets destroyed.

To avoid use-after-delete, we will use an SwClient on field types, thus
detecting if a collected field type got destroyed; iterating over fields
using SwIterator is safe, because removing a node with fields would update
the iterator.
