Add `verify_base_db` method to check if all base tables are present. 

Optionally, also adds a notice in case all db tables are not present. Returns list of tables.

Note that we only check missing tables and don't care about exact table structure because many time tables are modified by merchants to better suit their needs (indexes, collations etc).
