3.1.6 multiserver: creating a mysql of a user when the database is canceled

When deleting the mysql database, the user is also deleted from the mysql server.

When I create a new database and assign it to the user's ispconfig, it will not be created on the mysql server.

After starting the resynchronization does not occur on the server to create a mysql user

Resynced Database User Nothing found

when viewing web_database_user, all users have server_id = 0
