Removed leading 0 from array initializer

subscribe() uses the array initializer to execute the template function
subscribeToType() for every parameter in the parameter pack of the
variadic template function 'subscribe()'.

A leading 0 was included in the array initializer. However it serves no
function. I've removed the 0 in this commit.
