fix: Fixing tools working with generative-ai (Google) and streamText

[Yaroslav Beletsky]

Feature Description

When using generative-ai from Google and streamText from ai, the Stream receives a message about the end of the Stream. But this is not true, since after discovering new functions in the LLM response, the exit status of stream must also be changed

My suggestion

The hasToolCalls flag is used earlier for any chunk candidate that has a finishReason.
