dc6732ef04 Refactor the SNTApplicationTest unit tests to function correctly (#885)
* Refactor the SNTApplicationTest unit tests to function correctly.

The tests were originally written in a table style and were impacted by the lack of mocking the configurator. This caused issues with static rules to impact the unit tests.

Additionally added improved logging messages for critical binaries and a todo for macOS 13 unit tests.

Added goodbinary and rules.db test files to allstar's ignored paths.

10f2d852f5 Add functional test for executing a binary on SNTApplication. (#562)
This adds a full functional test for starting up an SNTApplication
(with as few mocks as possible) and executing it with a directly
recorded & collected EndpointSecurity event.

This also fixes a potential race condition and segfault on Santa startup: due
to es_subscribe being called first, it's possible for an es event to arrive
before listenForDecisionRequests or listenForLogRequests are called,
causing the SNTEndpointSecurityManager callbacks to call a nil pointer.
