Can't get whole string if start with number

[jma1987]

Please ensure the following information is supplied for new issues:

• [ ] Riak Node.js Client version 2.4.0
• [ ] Node.js version 6.11.3
• [ ] Riak version Unknown
• [ ] Operating System / Distribution & Version MAC
• [ ] Riak error.log file, if applicable
• [ ] What commands were being executed during the error Search.prototype.onSuccess = function(rpbSearchQueryResp)
• [ ] What you expected to have happen We can't get whole string if it's start with number. For example 123abc, we get 123 when executing search. Root cause is we need to check it's a whole number or not first. The method is "function maybeIsNumber(n)" in utils.js. Please see my pull request. #188

Thank you!
