[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.
