AuthRequestParams with non-null resources List throws json parsing error

[bobwith2bees]

Steps to Reproduce

• Create DAPP Auth request similar to README, but populate the resources parameter on the AuthRequestParams.
• On Android open the URI with Rainbow and Accept
• The response from the wallet appears to have a parsing problem.

Workaround

• Do not populate the resources parameter. (keep it null)

    final AuthRequestResponse authReq = await _wcClient.requestAuth(
      params: AuthRequestParams(
        aud: 'http://localhost:3000/login',
        domain: 'localhost:3000',
        chainId: 'eip155:1',
        statement: 'By signing in you are demonstrating to ${kAppName} you are the owner of the account selected. No account connection, access, or permissions in any form is granted by this EIP-4361 request.',
        nbf: notBefore.toIso8601String(), 
        exp: expires.toIso8601String(),
        resources: ['https://eips.ethereum.org/EIPS/eip-4361'], // kb articles etc
      ),

Yeah, I'll be honest there isn't a test that includes resources, so I'm not surprised.

Let me add your resources to the tests I'm running and fix the issue.

Updated to explicit json and added tests, this should be resolved with 2.0.13
