[evolution-data-server/openismus-work-master: 6/6] Adding test that fires up multiple EBookClientViews

[Tristan Van Berkom <tvb src gnome org>]

commit 58bcd2b437e6c2c1b9da3ff10eb11f25f9cc6a25

    Adding test that fires up multiple EBookClientViews
    
    This indicates there is currently a problem when some views are opening
    a direct SQLite connection and the server is querying the existing contacts,
    the server can get 0 results in the case other clients are concurrently
    connecting.
