Error while resend account confirmation link with special chars (e.g. "+" in email)

[cviking26]

There is an error while click on "resend confirmation mail". The mail address will transfered without special chars like "+". This is important for the new gmail feature which provides simply adding aliases.

Preconditions

1. Magento 2.1.2
2. Enable Double-OptIn Mails for Customer Registration

Steps to reproduce

1. Register as a new Customer with email like "firstname.lastname+PARAM@gmail.com" (customer/account/create/)
2. After Redirect to customer/account/login/ click on "Resend Confirmation Link"

Actual Result

3. This redirect to customer/account/confirmation/email/firstname.lastname+PARAM@gmail.com/ - The Parameter email in url is not urlencoded, so the param is missing in the input field.
   Parameter on this page in input field is now "firstname.lastname PARAM@gmail.com" without the plus

Expected result

1. Click on "Resend Confirmation Link"
2. Get URL encoded mail in input field on customer/account/confirmation/email/firstname.lastname%2BPARAM@gmail.com/
   so Parameter in input field is with "+" char e.g. "firstname.lastname+PARAM@gmail.com"

Solution

Bug can solved simply adding "_query" in htdocs/vendor/magento/module-customer/Model/Url.php:221

return $this->urlBuilder->getUrl('customer/account/confirmation', array('_query' => ['email' => $email]));
