Warden's dig cooldown unconditionally resets on sniff

When a warden attempts to sniff out a target, its dig cool-down timer will reset, regardless if its anger increases or not.

In a normal survival scenario, this results in the warden not despawning even if a player is taking the intended steps to avoid being detected.

Reproduction:

1. Load a new creative world.
2. Spawn a single warden.
3. Switch to survival mode
4. Allow the warden to sniff the player out, but keep at a distance such that it does not get angry at the player.
5. Run the following command twice: once before the warden finishes its sniff animation, and once after it has found a target:

/data get entity @e[type=minecraft:warden,limit=1] Brain.memories.minecraft:dig_cooldown.ttl 

**

Expected Result:

The warden's dig cool-down will continue to count down if the warden was not angered after sniffing a target.

Observed Result:

The warden's dig cool-down resets even if it was not angered by sniffing a target.
