The Wandering Trader spawn egg incorrectly generates an additional Llama Trader

In Minecraft Bedrock Edition, when using the "Spawn Wandering Trader" egg, an additional Llama Trader incorrectly spawns instead of just the Wandering Trader. However, the "Spawn Llama Trader" egg works perfectly.

This appears to be a bug that was overlooked when the Llama Trader spawn egg was added.

Observed results:

In Minecraft Bedrock Edition, when using the "Spawn Wandering Trader" egg, the Wandering Trader and an additional Trader Llama incorrectly appear instead of just the Wandering Trader.

Expected results:

The Wandering Trader spawn egg exclusively spawn the Wandering Trader villager, according to the intended mechanics.
