#80 Calender events get multiple entries upon synchronisation

[Joran]

When I synchronise my calendar in Thunderbird, events sometimes get multiple entries in my Lightning/Sunbird calendar. I.e. I see the same event, say three times after synchronisation. Strangely this doesn't happen always and I have not yet been able to recognise a pattern behind this behaviour. However, the bug is reproducible in different accounts. I use the latest version of the plugin, i.e. v0.9.1

I've attached the log (note that I've deleted part of all occurrences of my IP address, so this is intentional).
