Krzysztof Kotlarek f530378df3 FIX: Restore for non-multisite is not raising an error on reconnect step (#8237)
That commit introduced a bug to the system: f69dacf979

Restore works fine for multisite, however, stopped working for non-multisite.

Reason for that was that `establish_connection` method got a check if the multisite instance is available:
```
    def self.instance
      @instance
    end

    def self.establish_connection(opts)
      @instance.establish_connection(opts) if @instance
    end
```
However, the reload method don't have that check
```
    def self.reload
      @instance = new(instance.config_filename)
    end
```

To solve it, let's ensure we are in a multisite environment before call reload
