The `EntityFrameworkStore.DeleteManyAsync` throws error with database other than SQLite since Elsa 2.9

Hi there, after upgrade to Elsa 2.9.0, some error happens.

1. Unable Bulk delete workflow instances.
2. Unable publish workflow definitions.
3. The CleanupHostedService Failed to perform cleanup.

It may caused by #3286

@sfmskywalker With the latest preview from myget, we getting the following error. Our database is not named Elsa, is the Elsa. a accidental missed hardcoded database name in the query?

Microsoft.EntityFrameworkCore.Database.Command[20102] Failed executing DbCommand (0ms) [Parameters=[@p0='?' (Size = 4000)], CommandType='Text', CommandTimeout='30'] DELETE FROM Elsa.Triggers WHERE ``WorkflowDefinitionId`` = @p0

Unhandled exception. MySqlConnector.MySqlException (0x80004005): DELETE command denied to user 'elsa_workflow'@'rt1-worker3-221cd339-4qchr.k8s.local.net' for table 'Triggers'

Hello , I think this should be fix with #3345. Indeed , I’ve seen during my test the issue when we don’t use the default database name. And because the notion of schéma is not the same for MySQL , we can remove the schéma name from dbcontext when we use MySQL to avoid this issue.
