Adds changes to be atomically applied to the specified row if the condition does not yields any
cells when applied to the row.

<p>Each {@code mutation} can specify multiple changes and the changes are accumulated each time
this method is called. Mutations are applied in order, meaning that earlier mutations can be
masked by later ones. Must contain at least one entry if {@link #then(Mutation)} is empty, and
at most 100000.
