🐛 Bug Report: Profile image not loading for invited team member

[ChiragAgg5k]

👟 Reproduction steps

1. Invite a user to your team.
2. Image doesn't show

👍 Expected behavior

It should show an image.

👎 Actual Behavior

Image isn't showing. Here is the error from network call:

{
    "message": "Invalid `name` param: Value must be a valid string and at least 1 chars and no longer than 128 chars",
    "code": 400,
    "type": "general_argument_invalid",
    "version": "1.6.1"
}

So this happens because the url https://cloud.appwrite.io/v1/avatars/initials?name=&width=80&height=80&project=console&name=&width=80&height=80&project=console
has the name parameter as none, since the invited user's name wasn't specified (it was optional)

Similar to #1598, we should fallback to using the email address for the name param if there is no name.
