Describe the bug
An Azure AI agent will enter an infinite loop when a tool is not found in the kernel.

To Reproduce

1. Created a regular agent, with functions, in Foundry through the SDK (azure.ai.projects)
2. Referenced this agent from Semantic Kernel as follows:

agent_definition = await client.agents.get_agent("...")
sk_agent = AzureAIAgent(client = client, definition = agent_definition, plugins = [])

The plugins argument is set to an empty list intentionally because the tools are in the agent definition.

Expected behavior
Semantic Kernel Azure AI agent should throw if a tool is not found.
