chore: unknown flags should not include flags that exist in Unleash (#10568)

Browse Source 
https://linear.app/unleash/issue/2-3825/fetching-unknown-flags-should-not-include-flags-that-currently-exist

Fetching unknown flags should not include flags that currently exist in
Unleash.

This is especially noticeable if you create a flag with an unknown
flag's name, since it won't go away from the list right away.
