sw floattable, insert UI: fix missing undo/redo

There were 3 problems here:

1) SwDoc::MakeFlyAndMove() declared that inserting fly frames is broken
anyway, so just deleted the whole undo stack. Remove the
DelAllUndoObj() call, so the underlying problem is visible.

2) MoveNodeRange() had a flag to create undo objects, but this flag
wasn't used.

3) The empty text node after the table in the just created fly was
removed using a call to SwNodes::Delete(), which is not undo-aware,
so the table was inserted after the anchor (and not before the anchor)
on undo. Fix this by going via sw::DocumentContentOperationsManager that
knows how to delete while working with the undo.

Do this unconditionally, because the 2 callers of this function is just
SwFEShell::NewFlyFrame() (UI) and SwXFrame::attachToRange() (UNO API,
mostly the DOCX import), probably both want proper undo support.
