Fixed Magento installation with MySQL 8.

Fixed Magneto installation with MySQL 8.

Fixed Issues (if relevant)

It was impossible to install Magento 2.3.3 with MySQL 8.
The cause of this issue was a forced indexation triggered by the DB patch.
The first time indexation may cause DDL scripts execution. At the same time, Magento wraps DB patches with the transaction.
As a result, Magento tries to open a new connection to perform DDL, and the original transaction does not see a table that created after the transaction started.

Reasonable workaround - do not invoke indexation from the patch. If necessary, the indexer can be invalidated.
This is a safe operation that does not require DDL execution and could be invoked from the patch.
