Populate refs for console view

The console view is currently broken [1] with an error that seems
incorrect:

"incorrect repo URL "https://gerrit.googlesource.com/luci-test" in the
config or no access"

The docs [2] say that refs will default to ["refs/heads/main"] anyway,
but I see other hosts setting it. I would like to see if this fixes the
console view.
