When the turtle file is corrupted WiredTiger will delete it and restore it from the metadata (code here). However, this raises an issue when we're in the middle of a live restore as the LR state is only stored in the turtle file.

We need to review how we can handle this failure case, in including:

• What cases can lead to corruption and recreation of the turtle file
• What the system looks like at this point in time
• Tests to reproduce these cases
• Determining if there is other metadata like the LR state that would face the same issue, and how it is recovered
