chore: improve test tools for liquidation.ts (#9641)

closes: #XXXX
refs: #XXXX

## Description

Currently liquidation.ts only allows placing bids in the beginning of the test flow which causes conflicting offer ids if there are 
newer bids. In this PR we offset those bids by defining a `base` variable.
