[BUG] Application ``icon_url`` property returns an error when none of any picture is set for the application on discord.com/developers

[B1ue-Dev]

Describe the bug.

Previously, on Pull Request #656, I added a property to get the Application's icon URL with icon_url. However, I realized that I understood the wrong way between how Application icon and user icon works. My bad first.

Next pull request will be for fixing this specific problem.

List the steps.

1. Remove all picture/avatar on the Application.
2. Get bot.me.icon_url.
3. Print out the Application's picture URL.

What you expected.

I was expecting to see the returned URL.

What you saw.

I got this from the terminal:

Task exception was never retrieved
future: <Task finished name='Task-16' coro=<test() done, defined at .\Articuno\bot.py:30> exception=AttributeError("'Application' object has no attribute 'discriminator'")>
Traceback (most recent call last):

    url += f"embed/avatars/{int(self.discriminator) % 5}.png"
AttributeError: 'Application' object has no attribute 'discriminator'

What version of the library did you use?
