More informative error message for createSelector

[RusinovAnton]

I've just had a case when I misused createSelector by mistakenly passing resultFunc into array with inputSelectors.

createSelector([
  firstSelector,
  secondSelector,
  (firstParam, secondParam) => {
     ...
     return { ...derivedProps }
  },
])

And error message I had is bit confusing

resultFunc.apply is not a function

and it took me a while to define what exactly caused this error.

I propose to add error in case when resultFunc is not a function to make it more clearer to find and fix mistakes like this.
