fix get_user calls fail when no session or jwt is available

[jantznick]

What kind of change does this PR introduce?

Fix #314

What is the current behavior?

Currently an error is returning from supabase request

What is the new behavior?

My update short circuits to prevent the supabase request from being made if there is no jwt and no session

Additional context

This mostly follows the logic of the get_session calls

Since it may not be obvious, my use case is a server side auth handler. Flow is as follows

1. User logs in, flask adds cookie with jwt to request, user logs out <- after this there is no active session on the supabase client
2. Future calls contain the jwt, flask takes the token and checks with get_user() if the user is valid <- this is where bug is happening, if an unauthenticated user attempt to view a page or api they should not be able to view as they won't have a jwt in the request

Flask route info causing the break:

@app.route('/user_profile', methods=['GET'])
def user_profile():
    jwt = request.cookies.get('auth') or ''
    res = supabase.auth.get_user(jwt)

Hey,

Thanks for the PR! Do you mind running the pre-commit hooks on this? After which I think it's good to go.

[jantznick]

@J0 yep, unsure if I did it correctly as I've never done it before, but when I did it just 'changed' the changelog but no diff was showing in my IDE, looks like it's the same. Anyways I think the test is passing now but was failing before so maybe it's right?

@jantznick

I think it's just the line endings so it probably won't show up. It should be fine now and good to go. Thanks! Appreciate you taking the time to improve gotrue-py
