Bug: Consumer chain validators are not as expected for top N = 100

Problem

Bug reported by @fastfadingviolets via Slack

In the test scenario presented in the new e2e test, namely:

provider chain with max_validators=5, max_provider_consensus_validators=4
validators with powers 30, 29, 20, 10, 7, 4
a consumer chain with top N=100
then validators 30, 29, 20, 10 should have to validate on the consumer chain.

The previous behaviour was that validator 10 did not have to validate, and only 30, 29, and 20 had to validate.
