FileAlternationMonitor#stop() not stop the thread
The thread if FileAlterationMonitor wasn't stopped by the `stop(int)`
method, which forbid application to shutdown unless all `Thread` are exited (if
FileAlterationMonitor is part of a DI managed component).
This behavior conflict with the method javadoc `@param stopInterval the
amount of time in milliseconds to wait for the thread to finish.`
### Simple exemple to understand
```java
Thread t = new Thread(() -> {
try {
Thread.sleep(500000);
} catch (final InterruptedException e) {
}
});
t.start();
t.join(50);
// Ok, we reach this point until 500000ms are elapsed, but the thread is
still alive.
// because Thread#join(int) does not kill the thread. And the thread
remains alive.
```
```java
Thread t = new Thread(() -> {
try {
Thread.sleep(500000);
} catch (final InterruptedException e) {
}
});
t.start();
t.join(50);
t.interupt();
// Thread is exited
```
In this case, we waited the given time BEFORE exiting the `Thread`, as
described in the javadoc, and the `Thread` is now finished and killed.
