sw: WW8 import: properly handle consecutive range annotations

moz1187869-1.doc crashes on export to ODF because an annotation
mark has been inserted that does not have a SwPostItField.

In fact, the SwPostItField exists, but the annotation mark is at
the wrong position.

There are 2 consecutive range annotations in the file, so when
Read_And() calls MoveAttrs(), the end of the both annotations
are moved 2 times, hence later SwFltControlStack::SetAttrInDoc()
will insert 2 annotation marks with the same end position,
and the 2nd one will overwrite the name that the 1st one set
on the 2nd SwPostItField, while the 1st SwPostItField remains
with an empty name.

Ensure that the end of an annotation mark is no longer moved
once it's on the position of the field inserted in Read_And().

Crash is a regression from 31c54fa7bb03768b425ae019096e0a0e26e9c736.
