fix(oauth2): handle redirect params properly

[fernandolguevara]

Given the following URL after user logged in using casdoor, the UI app can not validate (checking the state param) the response bc an error parsing the params

redirect with hash
---
http://.../static/oauth2-redirect.html#token=eyJhbGci....?state=TW9....Sk=&token_type=bearer

before:

        if (/code|token|error/.test(window.location.hash)) {
            qp = window.location.hash.substring(1);
        } else {
            qp = location.search.substring(1);
        }

after:

        if (/code|token|error/.test(window.location.hash)) {
            qp = window.location.hash.substring(1).replace('?', '&');
        } else {
            qp = location.search.substring(1);
        }

btw, the default behavior on oauth2 would try to get the value for access_token property from the oauth response if you are using a different name for the TOKEN property, it should be specified under components/securitySchemas/<key>/x-tokenName

components: {
        securitySchemes: {
          casdoor: {
            type: 'oauth2',
            'x-tokenName': 'awesomeTokenName', 
            flows: {
              implicit: {
                authorizationUrl: `http://blablabla/login/oauth/authorize`,
                scopes: {},
              },
            },
          },
        },
      }

@fernandolguevara Thanks for the PR! I assume this change also needs to be propagated to /dist/oauth2-redirect.html as well?
