Updates test expectations for stack traces. (#51185)
With --lazy-async-stacks the stack output has changed slightly so updating the expect files to match.
This is a follow-up to https://github.com/flutter/flutter/pull/51047 as a preparation for the next engine roll which will start enabling --lazy-async-stacks in JIT mode.
