Drop MailPoet tables when a site is deleted in a multisite install

Browse Source 
This commit makes sure MailPoet tables are dropped when a site is
deleted in a multisite install. It uses the filter `wpmu_drop_tables`
to add the list of MailPoet tables to the list of tables that WP drops
whenever a site is deleted in a multisite install. $wpdb is used instead
of Doctrine entity manager as the latter is not affected by calls to
switch_to_blog() which is used in this case to switch from the main site
to the site being deleted.

This will only work if MailPoet is network active. If it is not,
MailPoet code is not executed inside the WP network admin panel,
and thus our filter is not added to wpmu_drop_tables, and MP tables
are not deleted.
