Fixed websocket connection and falback mechanism

[razvantomegea]

Issue

Websocket not reconnecting after logout and the fallback mechanism (polling interval) is not triggered.

Reproduce

1. Login with one address;
2. Logout
3. Login back with another address.

Actual Result: "Websocket reconnecting..." message appears (it should not when logged out)
Expected Result: "Websocket connected" message appears (after logged in again)

Root cause

• The old address is checked within the functions (hooks closure);
• There is not check for previous websocket status to see the change differences in the fallback mechanism;
• Websocket connection status is not reactive to trigger fallback mechanism on webscoket connection failure.

Fix

• Fetch the address directly from store in the functions (setTimeout and setInterval);
• Make the WebsocketConnection reactive.

Additional changes

• Added useWebsocketPollingFallback to reuse the polling interval fallback mechanism
