[BUG] Scaffold/tower won't place certain items the player is holding

[Trattue]

Scaffold and tower won't place blacklisted items the player is holding in certain cases.

1. Hold a blacklisted item (for example torches) in your hand.
2. Have no not blacklisted items in your hotbar.
3. Enable the tower/scaffold setting autoblock and the module itself.

In contrary to this, blacklisted items in the player's hand will get placed when autoblock is disabled or other not blacklisted items are in the hotbar (for example stone).

Should get fixed by #117
