Cannot access nautilus-sendto repository with HTTPS

[藍挺瑋 <lantw44 gmail com>]

Hello,

It seems that all nautilus-* repositories on git.gnome.org became 
inaccessible after nautilus was moved to GitLab. It is still possible to 
access these repositories with GIT or SSH protocol, but I hope we can 
keep HTTPS protocol working.

$ jhbuild buildone nautilus-sendto
