Remove buildAuthorizeUrl

[frederikprijck]

Changes

This PR removes buildAuthorizeUrl. This method was introduced to allow external redirect when logging in, this has now been supported through using onRedirect when calling loginWithRedirect.

Any code that uses to rely on buildAuthorizeUrl:

const url = await client.buildAuthorizeUrl();
// pass url to anything that opens the url

Should be updated to use onRedirect():

await client.loginWithRedirect({
  async onRedirect(url) {
    // pass url to anything that opens the url
  }
})

With the removal of the fact that calling buildAuthorizeUrl created a transaction, this method is now less useful as it can not be used to start the login flow, because of the fact that the SDK will not be able to handle the callback due to missing transaction. Therefor, removing it makes sense as it was initially introduced for the reasons covered in the alternative (using onRedirect).
