emit_trigger() should trigger when a file moved to a destination under watch

[bob-rove]

The issue appears when performing a file move operation from not watched to a watched destination.

Expected behaviour: if destination file path in move operation appears to be watched (while source file path is not), pytest-watcher should trigger pytest.

Here is an example of events appearing when using unison tool, which is syncing changes to remote destination by first creating a temporary file and then renaming it to a destination:

2022-10-17 15:32:18 - Moved file: from ./tests/sites/.unison.test_discover.py.7f0384dc585055b3fcfb405908d8de58.unison.tmp to ./tests/sites/test_discover.py

These events gathered with watchdog example code here: https://pypi.org/project/watchdog/

The fix seems to be pretty straightforward - just extend the condition in process_event method to something like this:

    def process_event(self, event: events.FileSystemEvent) -> None:
        if _is_path_watched(event.src_path):
            emit_trigger()
        elif event.event_type == events.EVENT_TYPE_MOVED and _is_path_watched(event.dest_path):
            emit_trigger()

Hey @bob-rove
Thanks for pointing that out,
I'll take a look

@bob-rove
Corresponding changes have been merged and new version released! Thanks, once again

🚀 Awesome! Thanks a lot @olzhasar 🙇
Now it's playing well with Unison and similar sync strategies 👍
