Inconsistent errors and error messaging

[tripott]

• Attempting to Add the following to the /shoes endpoint produces a 500 internal server error but displays a 400 error message. Need a consistent and correct response and error message to help the developer troubleshoot their call to the api.

• Adding a duplicate shoe provides a 400 No Data to Add error message and a 500 internal server error. 500 internal server errors are meant when an error occurred on the server. 400 series are for when the developer who is calling the api send bad data in the request (such as missing or in this case duplicate data.)
