SIM900 throws error after resetting and re-connecting.

I updated my version to get rid of self caused memory leaks, I use the immediate return for timeouts. Thanks to the fix to the SIM900 module it is so far quite stable.
Additionally I set the SIM900 baud rate to 9600. Additionally I pull jobs out of resources with the max=1 parameter, means get only as less data as possible.
Memory seems stable so far.
I put the code online: https://github.com/afitterling/espruino-­projects2/blob/master/RemoteWateringSyst­em.js
The cariots module can now handle wrong JSON and will reject the successful call:
https://github.com/afitterling/Espruino-­Modules/blob/develop/carriots.js
this is the result of the status push at call 104.
