Add player hear self tests.

Atan doesn’t currently provide a callback for when the player hears
himself, so the test only expects that the parser doesn’t raise an
error. If anything is called back, the test will fail.

This is something that will need to be fixed before v1.0 can be
released.

Not very extensive at the moment.
Ignore the player hear self/others tests for now until the parser is fixed.

This just aids in development of tests by making it clearer if newly
added tests are failing.
