The SQL wrappers of the module relied on stringToNode(), that trusts
its input. When specifying node strings that to not match with the
expected ExtensibleNode "TestExtNode", the module would crash.
This adds a simple set of sanity checks to check the input, ensuring
that only an ExtensibleNode "TestExtNode" goes through. Though far
from critical, it's always nice to make these test modules not crash
when used.
