Fix `check-test-warnings` workflow: "Global state has changed" in `test-report.brmsfit` about report

[rempsyc]

It seems this issue arises simply from calling the brms::brms() function. Just running the test with:

model <- suppressMessages(suppressWarnings(brms::brm(
    mpg ~ qsec + wt,data = mtcars, refresh = 0, iter = 1, seed = 333)))

Generates that "Global state has changed" warning. Any pointers here @IndrajeetPatil? Would you suggest opening an issue in the brms repo?

Sorry, missed this.

I see that you have already created an issue.

Let's see if there is any upstream change that takes care of this. If not, we need to think about an alternative strategy to figure out that our code is not changing global state anywhere. Because if just a namespaced function call changes state, there isn't much we can do about it.

Maybe we need to restrict this check only to tests that use easystats packages.
