[BUG] DB closed to early in 6fb5700

[Łukasz Żarnowiecki]

Hello again,

While I was testing my Python3 branch atop next I noticed that the
commit 6fb5700 introduces bug when running offlineimap without "-o"
switch.  On second loop iteration it complains that the database was
closed so no operations could be performed on it.

I did not look into the code yet (lack of time, sigh), but it seems like
a database is closed to early.

Regards
