Fix the Neutron functional job for stable branches
Fix the Neutron functional job for stable branches

Change e06c18 caused the Neutron functional job to break for
stable branches. Even though the change was careful to avoid
the breakage, it looks like the test:

[[ ! $BRANCH_OVERRIDE =~ ^stable/(icehouse|juno)$ ]]

led to setting DEVSTACK_GATE_PROJECTS_OVERRIDE, even for stable
branches (as shown during the failed runs, e.g. [1]), thus
breaking the functional job.

This patch use the right variables instead.
