[pallet-broker] Fix auto renew benchmarks (#6505)
Fix the broker pallet auto-renew benchmarks which have been broken since #4424, yielding `Weightless` due to some prices being set too low, as reported in #6474. Upon further investigation it turned out that the auto-renew contribution to `rotate_sale` was always failing but the error was mapped. This is also fixed at the cost of a bit of setup overhead.
