When Dataset.map is called and the first examples processed return None, the writer is never properly initialized, causing a ValueError.

Fixes #7990
This PR fixes a bug in `Dataset.map()` where the writer initialization was incorrectly tied to the index being 0, causing crashes when the map function returns `None` for the first few examples and later returns a dict.
