    [FLINK-1937] [ml] Fixes sparse vector/matrix creation fromCOO with a single element

    The problem seems to be that Scala apparently cannot infer the correct type of a single
tuple in the presence of the overloaded method with the ```Iterable``` type parameter. If
one provides more than one element, then Scala knows that only the varargs method is applicable
and thus infers that the tuples have to be of type ```(Int, Double)```.
    
    One can solve this problem by specifying explicitly that the single tuple is of type ```(Int,
Double)```. However, to ensure a nice user experience I added a special case method which
takes a single tuple of type ```(Int, Int)``` and converts it into a ```(Int, Double)``` type.
