Description

In testing what happens in HA split brain scenarios, I ended up with an edits log that was named edits_47-47 but actually had two edits in it (#47 and #48). The edits loading process should detect this situation and barf. Otherwise, the problem shows up later during loading or even on the next restart, and is tough to fix.
