Jan Holst Jensen dd6165c8af Fix #2176: InChI functions should return NULL on un-InChI-able input molecules. (#2177) ...

* Add check of returned string from InChI helper functions and convert to NULL when blank string is returned (a valid InChI string or InChI key will never be blank).

* Since MolInchi() and MolInchiKey() will never return a NULL pointer, I have removed the check for NULL.
Hopefully the intent of the code is now clearer.
