[Bug] FolderDaemon doesn't work when blacklist pattern array is empty

[Sv443]

• .forEach loop isn't entered since this._blacklistPattern is an empty array.
• Additionally, the same file hash is probably added onto the promises array multiple times. A return after line 164 would probably fix this.

Temporary fix: set blacklist pattern to something that is a valid glob pattern but doesn't match any of the files, example: [ "**/path/that_doesnt/exist/*" ]
