[PATCH 1/3] send-pack: fix push.negotiate with remote helper

Commit 477673d6f3 ("send-pack: support push negotiation", 2021-05-05) introduced the push.negotiate config variable and included a test. The test only covered pushing without a remote helper, so the fact that pushing with a remote helper doesn't work went unnoticed.

This is ultimately caused by the "url" field not being set in the args struct. This field being unset probably went unnoticed because besides push negotiation, this field is only used to generate a "pushee" line in a push cert (and if not given, no such line is generated). Therefore, set this field.
