Lose trailing slash while create absolute url

[avkhozov]

• Mojolicious version: 6.66
• Perl version: 5.22.1
• Operating system: Ubuntu 16.04 LTS

Steps to reproduce the behavior

$ perl -MMojo::URL -le '$u = Mojo::URL->new("http://x.com/a/"); $x = Mojo::URL->new("?page=1")->to_abs($u); print $x;'
http://x.com/a?page=1

Expected behavior

Expected url is http://x.com/a/?page=1

Actual behavior

to_abs drop trailing slash, but browsers leave trailing slash when address bar has trailng slash and href attr contains only query string.
