fix(moduleExec): actually return coerced values :)

The previous `validateAndCoerceTypes()` would mutate the original object,
whereas `validateAndCoerceTypeBox()` returns a new object (which is
definitely better, but requires this little fix to make sure we actually
return the decoded types and don't just validate (like we do for "options",
for now).
