DATACMNS-899 - Fix recursion in ParameterizedTypeInformation.getMapValueType().

Browse Source 
Previously, calls to ParameterizedTypeInformation.getMapValueType() caused an infinite recursion when invoked on a type information that was not a map type. This lead to a StackOverflowError.

We now call the super method doGetMapValueType() instead of calling the entry super method getMapValueType() and return by that null in case the map value type is not resolvable.

Original pull request: #176.
