inspec report source_location data type

[alexpop]

When generating an exec report, the source_location field seen below:

inspec exec profile.tar.gz --format json
{
  "version": "0.24.0",
  "profiles": {
    "profile": {
      "name": "profile",
      "controls": {
        "tmp-1.0": {
          "source_location": [
            "controls/example.rb",
            8
          ],

is causing ElasticSearch import error if no data mutation is done:

"status"=>400, 
"error"=>{"type"=>"mapper_parsing_exception", "reason"=>"failed to parse", "caused_by"=>{"type"=>"illegal_argument_exception", "reason"=>"mapper [summary.source_location] of different type, current_type [string], merged_type [long]}}"

This is an enhancement request to change the data type for better report consumption.
