Fix: Working outside of request context

[dhanababum]

RuntimeError: Working outside of application context.

This typically means that you attempted to use functionality that needed to interface with the current application object in some way. To solve this, set up an application context with app.app_context().

https://github.com/python-restx/flask-restx/blob/master/flask_restx/marshalling.py#L251 --> this line is protected by has_app_context https://github.com/python-restx/flask-restx/blob/master/flask_restx/marshalling.py#L252 --> this line is not protected by has_request_context

I have integrated marshal_with serializer to database SQLAlchemy models But getting the RuntimeError: Working outside of request context

Corrected the code and successfully ran tox tests.

LGTM. Can you think of any cases where this could cause a problem? I can't think of any.
