      public String decode(String encodedStr)
      Decodes an encoded string from the JS Compiler ReplaceStrings pass.

      An original string with args might look like this: 

        Error('Some ' + arg1 + ' error ' + arg2 + ' message.');
      Which gets replaced with: 
        Error('key' + '`' + arg1 + '`' + arg2);
      Where ` is the argument place holder. The replacement mapping would be: 
        key → 'Some ` error ` message.'
      Where key is some arbitrary replacement string. An encoded string, with args, from the client will look like: 
        'key`arg1`arg2'
      Parameters:
      encodedStr - An encoded string.
      Returns:
      The decoded string, or the encoded string if it fails to decode.
