Espruino Wifi module not responding

@Coder2012,

used the binary approach and figured that 2.15, 2.17, 2.18 work. So I doubted my earlier confirmation that 2v19 failed. But: it kept failing... So now back to 2v18... (and some chat w/ @Gordon).

I noticed that connection could be made within the range of 8..12 seconds, but failing was always within 10..11 seconds:

Disconnecting from power and reconnecting power, Espruino-Wifi, upload-run test code usually made it 12 seconds... but also got 8 seconds versions...
