When passing a string that contains '%2B' the normalize method remove '%2B'

Example:

url = 'https://melianuncios-generic-s3-development.s3.us-east-2.amazonaws.com/dmfacessorios/MONITOR+FIXO%2BSENSOR+PRATA.jpg' Addressable::URI.parse(url).normalize.to_s
Return: "https://melianuncios-generic-s3-development.s3.us-east-2.amazonaws.com/dmfacessorios/MONITOR+FIXO+SENSOR+PRATA.jpg"

I found this PR related: #99

Addressable version: 2.7.0
