It was a big mistake I introduced in imapsync  release 1.468, I changed host1
connection to be read-only for safety I thought but it was a bad
idea within the context of --delete option, since --delete does change account1.

So take an older release than 1.468 or the any from 1.484 (included).
I also added a regression test about --delete so that this bad behavior
will never happen again.

I'm sorry for this ugly bug. I hope the read-only mode has the
side effect of not changing flags to \DELETED as well.
In case of flag change the effect of a second run could be catastrophic
because \DELETED flags would be synced to host2!
