Fix controller inheritance

Fix controller inheritance

Description

Controller inheritance at the moment does not work when multiple controllers inherit from the parent controller because the child controller metadata is stored on the parent controller. This means that each of the child controllers will have the endpoints from each of the other children. This PR fixes this by storing the parent controller metadata on the parent, and the child controller metadata on the child. When the controllers are added to express, the parent controller metadata is fetched from the parent and combined with the child controller metadata.

Motivation and Context

This issue broke a CRUD generic controller on my project. I then found inversify/InversifyJS#854 and created a fix.

How Has This Been Tested?

The current unit test for controller inheritance has been extended to include multiple child controllers as well as the route info being printed to the console
