Patch that fixes one issue when removing folders

[Sergio Villar Senin <svillar igalia com>]

Hi,

I noticed that when moving a folder from one folder store to another the 
old folder store still thought that the moved folder was his child (for 
example when asking for child folders with tny_folder_store_get_folders)

The problem was that the CamelFolderInfo object located in priv->info 
was still there and was not regenerated after the move, so it kept 
caching the old children.

Find attached the patch that fixes it.
