Fix table restoration for compacted changelogs

[wbarnha]

Fixes #176.

@elrik75 how about giving this a try? Apparently the offset - 1 logic was around since the beginning of the project and I changed a unit test to accommodate this.

We'll need to test this further before merging.

Changes made

[wbarnha]

I reviewed the code and the problem is much deeper than the changes here.

[elrik75]

This bug still exists. I recently lost my rocks-db disk and Faust started and launched the recovery. Once again some changelogs partitions did not start (they have an offset equal to the first Kafka offset - 1). Removing the -1 saved me again. I didn't see any issue after the "fix".

[wbarnha]

In that case, I'll reopen the PR as a reminder for me to investigate this.
