[Db] Change to disconnect on initialise breaks tests where Db is used in _beforeSuite

[M1ke]

What are you trying to achieve?

A helper runs code to modify the database in _beforeSuite in order to add control rows before any tests are run.

What do you get instead?

The code crashes upon trying to run SQL as the connection has been terminated. This was new behaviour added by Codeception/Codeception@5e2c999

Easiest fix would be to create a public method on Db to ensure that the connection is open before running code if config has reconnect. The quickest route would just be to make connect() public.
