[core, react, vue]: Feature - Connect all previously connected wallets

[Adamj1232]

Description

Adds option to reconnect all previously connected wallets as an option.

Wallets will be reconnected in the order they were previously held within the array.

A new format is introduced within the PR for local storage saving of the wallet labels with an array of strings being used instead of a string. This will be the case regardless if the dev elects usage of autoConnectAllPreviousWallet or autoConnectLastWallet

type ConnectModalOptions = {
  ...
  /** 
   * If set to true, all previously connected wallets will store in 
   * local storage. Then on init, onboard will try to reconnect to 
   * each wallet with no modals displayed
   */
  autoConnectAllPreviousWallet?: boolean
}

Just one question around checking the list lenght

[leightkt]

When switching to this branch with a previously connected wallet in the demo project, I got this error:

I can only load the demo app after I clear my local storage and reload.

Once I refreshed the page- I was able to test and worked as expected- reconnecting all wallets I had connected.

Ahh yep, forgot to add a try block to one area, should be fixed now for backwards compatibility throughout. Thanks for catching that!!
