Confusing message when attempting to connect mismatched Delegate pins

When the user attempts to connect delegate pins that don't match, they received a confusing mouse tooltip message that simply reads "Delegate is not compatible with Delegate".

Suggested fix: When converting the pin type delegate to a string, we should include the signature too.

1. Open QAGame in editor.
2. Open the level blueprint.
3. Add a Set Timer by Event node
4. Drag the Delegate pin from Event Tick to the Delegate pin to Set Timer.

RESULT

The connection isn't accepted but provides "Delegate is not compatible with Delegate" message
