Christian Heimes 8b78abd6ef Accommodate changed pyasn1 behaviour
pyasn1 versions prior to 0.2.3 indicate absent value by returning `None` object, later pyasn1 versions use
the `noValue` sentinel object which is the basis for the `.hasValue()` method call (and .isValue property).

This fix makes the code compatible with both `None` sentinel and the `.hasValue()` test call thus making it
compatible with all reasonable pyasn1 versions in circulation.

Fixes RHBZ#1489184
