Fix Symbol#duplicable? for Ruby 2.4.0.
Ruby 2.4.0 has trouble duplicating certain symbols created from
strings via `to_sym`.
It didn't happen with `'symbol'.to_sym.dup` for some reason, but
works fine with the longer string sample.
Once a newer Ruby version with a fix is released we'll get have
a failing test case we can fix.
Ref: #27532
