Enhancement: Graceful Handling of Missing Controller Classes in GroupedEndpointsFromApp

[zfhassaan]

Summary:

This pull request addresses an issue in the GroupedEndpointsFromApp class where an exception was thrown if a route's controller class couldn't be resolved. The existing code was modified to return null in such cases, allowing for a more graceful handling of the situation.

Changes Made:

The following changes have been made in this pull request:

Updated the code to return null if the route's controller class doesn't exist.

Motivation:

The original code was throwing an exception when the route's controller class couldn't be resolved, which could lead to unnecessary disruptions and confusion. By returning null instead of throwing an exception, the code now gracefully handles scenarios where the class is missing, without causing unexpected issues.

Testing:

The modified code has been tested with various route configurations, including cases where the controller class exists and where it doesn't. Unit tests have been added to ensure that the new behavior is correctly implemented and that the expected return values are achieved.

Additional Notes:

No other changes have been made to the codebase apart from the modifications mentioned above.
