Let the workspace layout test's Lua assertions fail the suite

Lua 5.5's standalone interpreter exits 0 when the script that raised the error came in on stdin, and exits 1 for the same error in a script file. The block here was piped in through a heredoc, so every assertion in it reported as passing however wrong the value was: changing the expected layout to one the toggle never writes still left the file green.
