[BUG] Better manialink controller error handling

[araszka]

Describe the bug
If InvalidOperationException is thrown during the execution of a manialink controller action, the server controller is going to log a missleading No action found for route '...' error message.

To Reproduce
Steps to reproduce the behavior:

1. Create a manialink controller and a action to call
2. Throw a InvalidOperationException in the code
3. Trigger the manialink controller action

Expected behavior
The server controller checks for the existence of the action and does not soley rely on the InvalidOperationException class to determine whether an action was found.
