Invalid URL in Custom RPC input field breaks extension and needs to be fully reset

[TheBoroer]

Like the gh issue title says, if you copy and paste in a url with an invalid scheme/protocol and click continue without fixing the url, the extension breaks and repeatedly shows you a prompt that something went wrong. The go back button doesn't work at all, you're able to see/copy your secrets and other data out and then the only thing left to do is click the reset wallet button to do a full wipe in order to fix the issue.

There should be some sort of input validation + input error states to guard against this.

Example: ttps://example.rpc.com (missing the h from https)
