Thymio timers should not have priority over messages handling

[cor3ntin]

Consider the following code

timer.period[0] = 1
onevent timer0
  emit foo

Thymio will stop responding to any requests from the tdm (including variables change, description, tatus, etc), which means the thymio become completely unusable until it's rebooted

Seems to only be an issue on wireless - probably not fixable?

probably not I will have a look
