feat: improves the react connected hook when using extension & emit terminate when using extension

[christopherferreira9]

Explanation

This PR aims to improve the react connected hook when using the extension. Previously, the connected hook would always be true when using extension because window.ethereum.isConnected is always true as long as the extension is being detected. This now verifies if we have an account present meaning that it is actually connected to extension. If no account is present then it assumes it has been disconnected like mobile does (even though mobile relies on socket events to do this).

Main changes:

• terminate.ts. now emits a terminate event when extensionOnly is true (the current default)
• adds a new useHandleTerminateEvent.ts hook to handle the behavior of some connected hooks such as connecting and connected
• MetaMaskProvider.tsx now sets connected based on the existence of an account or not since window.ethereum.isConnected is always true if extension is installed

The Terminate event can also be caught from the dapp side when using extension:
