fix: Raise exception when tool call result is None (#1253)
# What does this PR do?

When there are issues with the tool call function, an exception is
raised but the error message is not informative. This adds a clearer
message to tell users to check their functions.
```
Traceback (most recent call last):
  File "/Users/phayes/projects/llama-stack/llama-stack/llama_stack/distribution/server/server.py", line 208, in sse_generator
    async for item in event_gen:

    async for event in agent.create_and_execute_turn(request):

    content=tool_result.content,
AttributeError: 'NoneType' object has no attribute 'content'
```

## Test Plan

Ran the same script and exception is raised with clearer error message.
