Fix posting notification to iOS Simulator (#2824)

rosen-vladimirov · web-flow · commit 649637fad788 · 2017-05-19T09:43:17.000+03:00
In case there are spaces in path to the executable (node) or in the args, we are unable to send notification. Replace the usage of childProcess.exec with childProcess.spawn, which handles the spaces correctly.
