r4bbit 974ec940d1 fix: ensure cooldownPeriod check is done correctly
The `FeaturedVotingContract` comes with a check in `initializeVoting()`
that aims to ensure that the community that the voting is being
initialized for, has not been featured previously for #n votings.

This is denoted as the `cooldownPeriod`. If `cooldownPeriod = 1`, this
means there needs to be at least one voting which doesn't include the
community in question, that came *after* the voting that did.

The internal `_isInCooldownPeriod()` check has a bug which will return
false positives for any communiy that has been featured before,
regardless of `cooldownPeriod`s value.

When iterating previous votings, the contract actually needs to start
with the last one and iterate downwards, however it does the opposite so
it will never reach the correct votings to check.

This commit fixes the check and adds two tests to cover the case
accordingly.
