[evolution] Remove SQLite mail summary migration.

[Matthew Barnes <mbarnes src gnome org>]

commit 12fab9c6a622398e40515ab8c8e8f2efd790fcd8

    Remove SQLite mail summary migration.
    
    It's been three years and it's standing in the way of our transition to
    keyfile-based accounts.  Users brave enough to jump to version 3.4 from
    2.22 or older will just have to re-generate their mail caches.
