Some tiny optimization for Realm unquoting

Benchmark.ips do |bm|
  bm.report('gsub') { '"My test Realm"'.gsub('"', '') }
  bm.report('tr') { '"My test Realm"'.tr('"', '') }
  bm.compare!
end

Calculating -------------------------------------
                gsub    25.497k i/100ms
                  tr    66.568k i/100ms
-------------------------------------------------
                gsub    384.830k (± 3.7%) i/s -      1.938M
                  tr      1.278M (± 2.7%) i/s -      6.391M

Comparison:
                  tr:  1278335.1 i/s
                gsub:   384830.3 i/s - 3.32x slower
