Observers have a 3 RS tick delay

This is a repost of MCPE-34207. Mega_Spud closed the ticket without realizing that it was his ticket. The issue still happens in the latest build. I was told to open a new ticket, since the original ticket is very old.

Verification builds:
1.7

Summary:
Observers in Bedrock have a 3 redstone tick delay, which is different to the Java version which has a delay of 1 redstone tick.

Steps to Reproduce:
See screenshots for setup

1. Run two observers into separate command blocks that run the command time query gametime
2. Observe the difference between the command block time output
3. Run test to the Java Edition, and observe the timing there

Observed Results:
In Bedrock, there is a 6 game tick (3 rs) tick delay on the observer output. In Java, there is a 2 game tick (1 rs) tick delay.

Expected Results:
The delay should be the same across versions wherever possible, so 1 rs tick.
