tdf#171191 sw redline render mode: fix crash on IME inputHEADmaster

Create a new Writer document, enable track changes, type "a", "1", "a"
with IME (pinyin) input, crash.

What seems to happen is that we have a transient redlie that's not yet
inserted into the redline table but already has its index assigned while
IME composition is in progress.

Fix this by simply handling this as if there would be no redline: once
the composition is done, we'll re-render anyway and that index will be
inside the bounds of the redline array anyway.

Regression from commit a24dd7b1d742ccd59768db8b6b6a522588952108
(cool#13574 sw redline render mode: avoid coloring, set lightness,
2026-01-15).
