#331 DataElement::GetValueAsSQ throws exception instead of returning nullptr

[Alder]

If gdcm::DataElement::GetValueAsSQ() is called for (0018,1008) tag then this function throws exception, which is unexpected, because in all other DICOM files that I have normally this function returns nullptr for every non-sequence data element.
