Wrong requeue order test

[erfan-mehraban]

It seems checking requeue order has logical problem.

ubroker/internal/broker/core_test.go

Line 248 in cb32497

s.Equal(messages[2].Message.Body, (<-delivery).Message.Body)

If we consume after publishing queue is like (front of queue) 1 2 3 (back of queue), requeue in order of 3 2 1 should results in this way:

requeue item	queue
3	3
2	2 3
1	1 2 3

But this function test it in wrong order. (3 2 1)

@erfan-mehraban You're right.. we should have prioritized items based on their ID's when we re queued. But I'm afraid it's too late to change that behavior :'(

@arcana261 Can we correct the test on PR?
