Update get-props test to be able to run in CI

In CI we put the working directory at /home/github/polaris/polaris

This double use of /polaris isn't compatible with the path normalization
that get-props does, it'll replace the first /polaris/ but not the
second, and so the files won't end up matching the snapshots in the test
file. To properly normalize this, we need to remove _any_ number of
/polaris/ path components in a row.

This didn't fail previously because this test wasn't part of a workspace
so it was never run in CI
