getUncleCountByNumber method
Block Uncle Count By Number The number of uncles in a block matching the given block number. If the method returns null a count of 0 is returned, this is to distinguish between this and an error.
Implementation

if (res[EthereumConstants.ethResultKey] != null) {
return EthereumUtilities.hexToInt(res[EthereumConstants.ethResultKey]);
} else {
