auto-update problem on test/fib-dbg.wasm.fromBinary

Running ./auto_update_tests.py should be a no-op, but it breaks test/fib-dbg.wasm.fromBinary, changing it so that check.py fails. It creates this diff:

Maybe missing a param or something in the auto-update script that is in check.py?

cc @yurydelendik , this is your code I believe.

Start with auto_update_tests.py and check.py, then inspect how test/fib-dbg.wasm.fromBinary is processed. Reproduce the issue with ./auto_update_tests.py and verify that the fixture remains unchanged and check.py passes afterward.
