…in one delta
OpenAIServingChat remaining-args backfill: when the entire tool call arrives in
a single delta, actual_call is empty after subtraction and
str.replace("", "", 1) returns the full expected_call, re-sending args the
parser already emitted. Guard that case (and skip overwriting delta_message
when nothing remains). Adds regression tests for the remaining_call logic.
Extracted from local commit 3cd2fb2f.
