Describe the bug

Problem: after adding a custom localhost network, if I change to another network and terminate the ganache server for localhost, I still can see how requests are being send to the localhost custom network together with the requests to the currently selected network.

Steps to reproduce

[investigating]

1. Setup a ganache server with a different port number than the default ganache port 8546
2. On MM, go to Add Network
3. Add the new server pointing to localhost 8546
4. Change to another network
5. Terminate ganache server
6. Observe network requests on the background console -- requests to the localhost net are still being sent, alongside with requests to the current selected network
