Fix resource utilization check in the CI (#1033)

Our CI workflows work by checking out the code from branch `gh-pages` to
retrieve benchmark results from previous commits and compare them to values
in the current run. However, the resource utilization check was done
after the benchmark result check which already has pulled in the branch
`gh-pages` resulting in errors because the branch already exists. This
change fixes that.
