[Users] Bad bug, moving a folder losts its content :(

[Francis Moreau]

Hello,

Ok, my first serious bug with Claws :(

When moving a folder from an IMAP account into a different folder inside the
same account, Claws moved the folder but all its content was lost :( !

It's 100% reproductible and doing the same move with Thunderbird works
perfectly fine.

Here's the network log when doing the move:
