Paging breaks when filtering with To number with + sign

[chadselph]

Issue Summary

When filtering a list of calls or messages by the to/from number, when including the leading + (E.164 format) the auto-paging breaks.

Steps to Reproduce

1. Get a number with more than 5 calls
2. Plug it into my example code.

Code Snippet

import com.google.common.collect.Iterators;
import com.twilio.Twilio;
import com.twilio.base.ResourceSet;
import com.twilio.rest.api.v2010.account.Call;

public class ReproduceTwilioBug {

    static {
        Twilio.init("xxx", "yyy");
    }

    public static void main(final String args[]) {
        final String to = "+1843xxxx";
        countCalls(to);
        countCalls(to.replace("+", ""));
    }

    static void countCalls(final String to) {
        ResourceSet<Call> calls = Call.reader().setTo(to).pageSize(5).limit(20).read();
        System.out.println("For " + to + " " + Iterators.size(calls.iterator()) + " calls.");
    }
}

This outputs

For +1843xxxx 5 calls.
For 1843xxxx 20 calls.

It's able to download the first page, but when it gets to page 2 (Page=1&PageToken=PG...) I get back calls: [] in the JSON. When I step through with the debugger the URL looks correct, and querying that URL with different HTTP clients (Insomnia, curl) returns the call records. I suspect the + is getting encoded into %2B too early and then getting encoded again.

Technical details:

• twilio-java version: 7.55.0
• java version: Adopt JDK 1.11.0-6
