tdf#140137 Don't throw exception when w:gridCol is missing "w" attr

2149e924cbc32c370128c5f87a4f55c50c99e6bd added a division-by-zero
check, which caused Writer to throw an error on the bugdoc.
Since the file could be loaded fine before, let's return to a
working version, with the check included.

The cause is the following in document.xml
(originating from a non-MS generator):
  <w:tblGrid>
      <w:gridCol/>
      <w:gridCol/>
  </w:tblGrid>

Word still splits such tables differently, but that difference
was always there in Writer.
