The Warp Stabilizer, 3D Camera Tracker and Roto Brush signatures hashed
the footage item's derived Debug text, so every new Footage field changed
every signature and dropped every saved analysis (placed_page did in 0.23).
Write the same text from a named list of fields instead: a new field no
longer compiles until it is decided there. Pin the text in a test.
