Enable automatic client reset handling for audit Realms

Audit Realms typically don't get client resets due to being very short lived, but restarting sync while one is partially uploaded can result in a bad client file ident error which also blocks uploading any other unuploaded files. Standard automatic recovery is very inefficient here - it redownloads the already uploaded data for the partition, bypasses the optimization to not actually apply the transaction logs locally, and then rewrites the transaction logs - but doing the optimal thing turned out to actually be pretty complicated and I couldn't get it fully working after spending more time on it than is justified.
