Fix tests broken by rapids-logger changes

[vyasr]

Description

#765 required an admin merge on this repository to break a circular dependency between this repository and rmm because rapids-cmake provides a centralized rapids_cpm_rmm function. Unfortunately, because of how certain tests in this repo were set up, they could not be tested against a fork (like #765 did) without manually copying over branches to the fork, so that was not done. Now that the rmm PR is merged, we can see that there are a few issues to be ironed out with the tests here. In particular, since rmm no longer clones fmt, the pin testing needs to be updated to not look for it.
