[gate-quickstart] Workaround for ansible bug 5504

Our gates in ci.centos currently fail when using depends-on in
both the extras->quickstart and quickstart->extras directions.

This patch addresses the extras->quickstart direction by
adding a workaround for a bug in the ansible git module when
using "force"
