    fixes unencountered bug in ample (#3237)
    
    Fixes a bug in Ample that no current code is encountering.  Ran into
    this bug while working on #3232 and trying to write new code that
    splits a tablet using conditional mutations. Fixing this bug in 2.1
    in case any new code is written that would encounter the bug.
