Check that lock file exists, before trying to delete it.

This need to be done, because when using FileLock::BLOCKING locking method, if there two separate process acquiring the same lock, when one finishes it deletes lock file, when next one finishes it throws "No such file or directory" exception, since lock file no longer exists.

thank you @denpamusic , can you add a test for this please ?

I'll try later this evening or on weekends. It'll be hard though, as php-vfs used for testing doesn't support blocking locks, as mentioned in the notes here: michael-donat/php-vfs#32.
I use php-lock run one crontab task at the time. Cron jobs I use tend to run only for 2-3 seconds every minute, blocking locks are great in this case, since locked process just waits for a few seconds instead of failing with exception and waiting for a whole minute.

you don’t need blocking lock for the test, you only have to acquire a lock, manually remove the file and release the lock

Thank you! It's easy then.
