[evolution-data-server/gnome-3-2] Add camel_folder_refresh_info()/_finish().

[Matthew Barnes <mbarnes src gnome org>]

commit 38d07d55a79f007d48ba6dd0e587850f7fdc9598

    Add camel_folder_refresh_info()/_finish().
    
    I forget to write wrapper functions for CamelFolderClass.refresh_info()
    and CamelFolderClass.refresh_info_finish() even though the class methods
    have been there for awhile.
    
    Thanks to Srini for pointing this out.
    
    (cherry picked from commit 1baddb8b7225cd3ea1cd186f663e859bfae84ba5)
