[Evolution] calendar refresh

[Xavier Bestel <n0made free fr>]

Hi !

I think that the 5 weeks displayed by the calendar are not enough, so each
time Evo is restarted I select (on the tiny calendar widget) 6 weeks (Id
like to ba able to selet more).

The problem is that when I have selected 6 weeks, the calendar redraws
without the appointments. It's not that important though, because as soon
as scroll it a bit, it'll refresh properly.
Still, it's a minibug.
