skypiax: insert the delay ONLY if the broken message is 'ERROR 92 CALL: Unrecognised identity': when repeatedly you try to connect to non-existing Skype account in a short period, the Skype client send you back the two halves of the message 'ERROR 92 CALL: Unrecognised identity' inverted in a way that breaks the flux of the API messages. Maybe an anti-spam feature? Anyway, let's try to work around it and restore sanity with a 1 second delay
