WSS Re-connection infinite loop

Bug Report

Currently, if a WSS Cloud App with a valid endpoint and invalid certificate is activated, core keeps attempting to re-connect to the cloud app.

Reproduction Steps

Setup test suite appJava with SSL enabled. Change the following params in Config.java

public static final TransportType TRANSPORT_TYPE = TransportType.WEB_SOCKET_SERVER;
public static final String APP_ID = "123e4567-e89b-12d3-a456-426655440000";
public static final String APP_NAME = "Test Suite SE";
...
public static final boolean ENABLE_SSL = true;
public static final String CERTIFICATE_PEM = "<server_certificate_string>";
public static final String KEY_PEM = "<server_key_string>";

Add cloud app entry for the cloud (with transport type WSS) in sdl_preloaded_pt.json. Replace <client_certificate_string> with an invalid certificate

"123e4567-e89b-12d3-a456-426655440000": {
            "keep_context": false,
            "steal_focus": false,
            "priority": "NONE",
            "default_hmi": "NONE",
            "groups": ["Base-4", "CloudAppStore"],
            "RequestType": [],
            "RequestSubType": [],
            "nicknames": ["Test Suite SE"],
            "hybrid_app_preference": "CLOUD",
            "endpoint": "wss://<core_ip>:4355",
            "auth_token": "none",
            "cloud_transport_type": "WSS",
            "enabled": true,
            "certificate": "<client_certificate_string>"
        },

Start Core and HMI
Click on cloud app entry in app list

Expected Behavior

Cloud app fails to activate
SDL sends BasicCommunication.UpdateAppList to the HMI with the cloud app endpoint and "cloudConnectionStatus":"RETRY"
SDL sends BasicCommunication.UpdateAppList to the HMI with the cloud app endpoint and "cloudConnectionStatus":"NOT_CONNECTED"

Observed Behavior

Cloud app fails to activate
SDL repeatedly sends BasicCommunication.UpdateAppList to the HMI with the cloud app endpoint and "cloudConnectionStatus":"RETRY"
SDL repeatedly sends BasicCommunication.UpdateAppList to the HMI with the cloud app endpoint and "cloudConnectionStatus":"NOT_CONNECTED"

NOTE: Core seems to sometimes send some invalid data to the HMI in the UpdateDeviceList request during this reconnection loop, such as "transportType":-1 and "cloudConnectionStatus":-1
