Fixes issue: InfluxDBResultMapper doesnt call POJO setter

[sjoshid]

Closes #670

Things included in this PR:

• Call field setters instead of setting field values directly.
• This PR maintains existing behaviour ie setting fields directly ignoring setters.
• Priority is given to field setter if one exists. If not, field is set directly.

@fmachado Im not sure if I need to run format sh. But when I do, I get a lot of diffs in most Java files. Anything I need to do with formattting?

@sjoshid thanks for submitting this PR.

Im not sure if I need to run format sh.

I don't remember when was the last time that I had to run that shell script as I'm using the checkstyle.xml for a while.

But before getting into the formatting issues, could you please check why Travis build failed?
