Whitelist and backlist should be case insensitive

[juntao]

We should do upper case comparisons when trying to match addresses to the whitelist or blacklist

filter logic was changed to:

filteredRes = Object.values(response).filter(function(obj){
            var lowerCaseBlacklist = blacklist.map(function (addr) {
              return addr.toLowerCase()
            });
            if(lowerCaseBlacklist.indexOf(obj._source.contractAddress.toLowerCase()) == -1)
                return obj
        })
