[MSC-108] Set the TCCL correctly and update tests.

Before calling start()/stop() on the service, the TCCL is set to the service's ClassLoader; before invoking listeners methods, the TCCL is set the the listener's ClassLoader. The same applies to LifecycleContext.execute(Runnable command), whereas the TCCL is set to the command's ClassLoader before invoking command.run().
Update tests accordingly to check that the TCCL is correctly set.

Update dependencies and POM
[AS7-2639] add to ServiceName.getSimpleName() to the exception message to give a hint to the problem
[MSC-111] The methods immediateDependencyUnavailable, immediateDependencyAvailable, transitiveDependencyUnavailable, and transitiveDependencyUnavailable should all check if the service is not being removed before notifying listeners and dependents.

Plus, add race condition tests for catching all those scenarios.
The children services mode should not be changed inside the parent's lock.

Or else we can get an assertion error:
