A band-aid solution for SI-5803.

Since ae5ff662, resetAttrs duplicates trees, which doesn't preserve ApplyConstructor.
My attempt to modify TreeCopier to do so proved trickier than expected.

In any case, ApplyConstructor is not long for this world, and is only used in tree printing
to distinguish `new X` from regular Apply trees, so this should suffice pending full surgery.
