Fixing Composer Dependency Issue

[nafiesl]

In this PR, we are fixing dependency issue which was reported on #51 @Maikuolan. If someone can help to verify this PR, it would be very helpful.

How to Test

1. Install this project (installation steps).
2. git fetch origin
3. git checkout fixing_dependency_issue
4. php artisan passport:install
5. On .env file, add these 2 variables:

PASSPORT_CLIENT_ID=2 # value from DB: oauth_clients.id
PASSPORT_CLIENT_SECRET=n8e2mBNiHllxxxxx # value from DB: oauth_clients.secret

6. Register new account
7. Use this curl sample to get an access_token:

curl -X POST 'http://dompet.test/api/auth/login' \
-H 'Accept: application/json' \
-H 'Content-Type: text/plain' \
-d '{
    "email": "your_username@mail.com",
    "password": "super_secret"
}'

8. Expected response:

{
    "token_type": "Bearer",
    "expires_in": 31536000,
    "access_token": "eyJ0eXAiOiJ...{long token}",
    "refresh_token": "def502008f7a...{long token}"
}

If we have no issue up to point 8, then this PR should resolve #51.
