Fix BlockDispenseEvent being called when nothing actually happens

[Machine-Maker]

The BlockDispenseEvent was incorrectly called in two specific situations, when bonemealing an invalid location, like a solid block or when trying to use flint & steel in an incorrect way. This doesn't match up with the rest of the calls of BlockDispenseEvent in which something always happens, and in other cases where something might happen, that logic is checked before calling the event.

Rebased for 1.20.4

Something that probably needs to be worked out is when exactly BlockDispenseEvent should be fired for a "failed dispense". A lot of items fallback to just being spit out if their "special action" fails, like glowstone being dispensed but the block in front isn't a respawn anchor. In this situation, dispenser with glowstone inside pointing at a non-respawn anchor block, the glowstone will be spat out. But if the block in front is a full respawn anchor, the dispense will "fail", not spitting out glowstone or refilling the anchor. Does BlockDispenseEvent fire in that case? Nothing happened, nothing changed, no item ejected, nothing. Unsure.
