Changes in EloquentTest for better experience for all developers

[saqlainkhadim]

i was doing test on my local machine but due to some issue with my db, i got some issues. then i decide to change the test file. I edited it and I think. if any other is suffering from the same error that will be resolved. there are no large changes just two small changes to check created record id instead of the hardcode id like 1 or 2.
