***Handle errors during stream restart in snapshot***

**Root Cause**
When `_restart_on_unavailable` caught a `ServiceUnavailable` or
resumable `InternalServerError`, it attempted to re-initialize the
iterator immediately within the `except` block. If this
re-initialization failed (e.g. due to a persistent transient error), the
exception would propagate unhandled, breaking the retry loop.

**Fix**
This change modifies the logic to reset the iterator to `None` and
`continue` the loop, forcing the re-initialization to occur inside the
`try` block. This ensures that subsequent errors during restart are
properly caught and retried.

**Testing**
Added unit tests to cover this specific behavior

PR created by the Librarian CLI to initialize a release. Merging this PR
will auto trigger a release.
