This pull request fixes the issue described in #11421.  It also adds a test for the issue.  The issue is present in 2.0 forward, but I decided to fix it on the 2.3 branch so that I could also write a test for it (2.0 had no tests for the Process component, and 2.1 and 2.2 didn't have tests for the `ExecutableFinder` class).

[Process] fix signal handling in wait()

wait() throws an exception when the process was terminated by a signal.
This should not happen when the termination was requested by calling
either the stop() or the signal() method (for example, inside a callback
which is passed to wait()).

``wait()`` throws an exception when the process was terminated by a signal. This should not happen when the termination was requested by calling the ``stop()`` method (for example, inside a callback which is passed to ``wait()``).

[EventDispatcher] don't count empty listeners

When event listeners for certain events are removed from the event
dispatcher, empty arrays are not being removed. Therefore, counting
on empty arrays leads to wrong results of the hasListeners() method.

Thanks to @mlindenb for discovering this an proposing a solution.
