tdf#91228 Fix Writer crash
Start Writer, Insert Image, Anchor as character, Go after
image, press enter, writer crash
This is because m_pAnchoredFly is not updated.
JoinPrev, JoinNext and SplitContentNode all rely on CutText with calls
InsertHint. InsertHint calls SetAnchor. SetAnchor calls Modify callback
except if "LockModify"ed. This patch ensures that, whatever the value of
LockModify, the references are kept correct.
