[Scripting] BlockCustomComponent#onPlace is called on block update

The `onPlace` method on block custom components is triggered when the block is updated (eg. state change) not only when the block is placed.

How to reproduce with test pack:

• Place the `testpack:test_block` block
• The block's `testpack:test_state` will be reversed every 10 ticks
• `onPlace` will warn "onPlace triggered" to the content log when it is called
• Observe
