[evolution-ews] Listen for change notifications only on user folders

[Milan Crha <mcrha src gnome org>]

commit 2c10cf22728043b54f1b1d3c3007b09ca2ca5421
Author: Milan Crha <mcrha redhat com>

    Listen for change notifications only on user folders
    
    The foreign and public folders cannot be used for change notifications,
    due to the server returning and error "A subscription can only be established
    on a single public folder or on folders from a single mailbox.", thus, rather
    than not having any change notifications, do listen on user folders only.
    The mail part did that already, only address book and calendar parts
    did not do it.
