Invalid Get request with non-existent filter returns all users

[Richard]

Using devstack all in one and running the get request:

curl -X GET 'localhost:35357/v3/users/?cake=isgood'

gives me back the entire user list instead of an error.
I also ran this query with httpie and this is what the neat
version of the output looks like:
