[PATCH] testbot: Fix the VM Missions validation.

[Francois Gouget]

$Item->Xxx("foo") does not go through PutColValue()!
Instead AUTOLOAD sets the specified property directly, maybe fori
performance reasons, and PutColValue() is only used by DBIBackend.pm.

WineTestBot::VMs was overriding PutColValue() to only revalidate a VM's
missions field if either the VM Type of Missions field were modified.
But instead ValidateMissions was always true after loading a VM from the
database (because of the PutColValue() calls), and not when creating a
new VM (in which case all the properties are set through AUTOLOAD).

So take a snapshot of the initial Type and Missions values when the
database code resets the IsModified field by calling ResetModified();
and then revalidate them whenever they have changed.
