Broken hook data

[mkabischev]

When we set initial coordinates for some object and these coordinates belongs to subscribed region data for inside hook is broken.

Steps to reproduce.

1. In first terminal

127.0.0.1:9851> nearby fleet FENCE point 33.5123 -112.2693 600
{"ok":true,"live":true}

2. In second terminal

127.0.0.1:9851> set fleet truck1 point 33.5123 -112.2693
{"ok":true,"elapsed":"68.993µs"}

Then in first terminal:

{"command":"set","group":"589af129375e4f2747a798ac","detect":"enter","key":"fleet","time":"2017-02-08T13:21:29.288927204+03:00","id":"truck1","object":{"type":"Point","coordinates":[-112.2693,33.5123]}}
{"command":"set","group":"589af129375e4f2747a798ac","detect":"inside","key":"fleet","time":"2017-02-08T13:21:29.288927204+03:00","command":"set","group":"589af129375e4f2747a798ac","detect":"enter","key":"fleet","time":"2017-02-08T13:21:29.288927204+03:00","id":"truck1","object":{"type":"Point","coordinates":[-112.2693,33.5123]}}

Second hook contains duplicated keys from first hook: command, group, detect.
