is-available route never responds with { "isAvailable": true }

[alina-vakulenko]

I am trying to verify if an email is already registered in the API before creating new user.
The response is always { "isAvailable": false } after sending POST request to https://api.escuelajs.co/api/v1/users/is-available
with object like
{
"email": "newtestuser@test.com"
}.
No matter what email address was typed in.

Steps to reproduce the behavior:

1. Go to "https://api.escuelajs.co/docs#/users/UsersController_isAvailable".
2. Click on 'Try it out'.
3. Type in email address that should be available.
4. See response { "isAvailable": false }

Expected response: { "isAvailable": true} for email addresses that are not present among users returned by "/users" URL.
