Description

Description

I see this error occuring in my logs quite a lot, I've somehow ended up with an empty file in my C:\Users\ewan\.appcelerator\appcd\telemetry dir, when trying to send the events appcd-telemetry chokes on this and fails to send. What we should do is wrap the JSON.parse in a try/catch if it throws nuke the file so we dont keep dying (the file on my machine is 2 days old)

Steps to reproduce

Run touch ~/.appcelerator/appcd/telemetry/c9bc717a-eeb1-4740-81cc-db5525c25ac4.json (might not work on Windows)

Watch the logs for events being sent

Actual

Chokes parsing a file

Expected

Should not choke and should remove file
