overdue: Sync.initSync misses retryable query

[oxzi]

Describe the bug

After updating and restarting almost every package, a race between the relational database and Icinga DB resulted in a failing query which is currently not being retried.

Lines 85 to 90 in a979409

	var rows []v1.IdMeta
	query := fmt.Sprintf("SELECT id FROM %s_state WHERE is_overdue='y'", objectType)
	if err := s.db.SelectContext(ctx, &rows, query); err != nil {
	return database.CantPerformQuery(err, query)
	}

Expected behavior

Same retry logic as everywhere else.

Your Environment

• Icinga DB version: 1.4.0

Additional context

In general, we should scan the code for SQL queries not wrapped in our retry logic. I would guess there are some more which can be wrapped safely.
