[pallet-broker] Fix auto renew benchmarks

[seadanda]

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.

Fixes #6474

TODO:

• Re-run weights

/cmd prdoc --audience runtime_dev --bump minor

[seadanda]

Since we advance to the fixed price phase, this is independent of the price adapter implementation and depends only on the config value set earlier in this file. Therefore it's better to unwrap here so the test fails, rather than always being mapped to Weightless.

This will affect polkadot-fellows/runtimes#490

Until this PR is merged and backported we should filter these calls and set MaxAutoRenewals to 0
