cocoa_bridge(run_key_action): Add newline to end of test map group

I keep forgetting to add the newline at the end, darn. Wasted a few
minutes of my time, but so cool that it's finally working now! The C
program now correctly prints the corresponding map.

Here's a diff of print debug statements I used to diagnose the problem:
