Optimize getEndingNodes

[mokeyish]

If there are multiple end nodes, only one needs to pass verification, and the others are automatically ignored.

This allows us to temporarily disconnect a node without deleting it.

You mean this allow us to disconnect one of the ending nodes without deleting it? But if you disconnect it, its no longer part of the endingNodes calculation no? Do you have a flow that can better showcase the issue?

When testing the prompt, the examples(for few-shot prompting) is no longer needed. ChatPromptTemplate node needs to disconnect the CustomFunction node(fetch the exmaples from vector database) so that it will no longer be executed.

The current version will consider this CustomFunction node to be an endingNode and prompt an error Ending node must be either a Chain or Agent.

this looks much neater! thanks a lot @mokeyish !

While only making check to get one validation for now, in future we should implement a validation on every component nodes level, instead of the getEndingNodes function at server level.
