fdo#62288 fix RTF import of table paragraph margins

Regression from 4a507f732d82c188ad81b022cbe3037951e58ac3. The problem
was that in some cases \pard can't reset all paragraph properties. The
original commit just made this keyword a noop when it occurred between
\cell and \row, but this is too much. At least margins do need
resetting.
