Subject: [PATCH] core: fix tests for checkInputVariables

The contract for this function has changed as part of the 0.12
reorganization so that, while before it would accept a partial variables
map if all missing variables were optional, it now expects that the caller
has already collected values for all variables and is just checking them
for type-correctness here.
