no warn for upcoming insight::get_data refactor

[vincentarelbundock]

Minor changes to tests in order to avoid warnings with this upcoming refactor of the insight::get_data function:

https://github.com/easystats/insight/pull/691

The issue is that we now recover data from the environment, which is much safer in model with transformations. This poses slight problems with testthat, however, since tests are run in weird environments. The tricks are to:

• Avoid using names like data and df which conflict with lots of internal objects
• Double assign in the data inside test environment: dat <<- Note that this assignment must occur after all transformations to the data.

I think this should be merged because the failures are already present in main and are unrelated to this PR.

I don't have merge right on this repo, so I can't do this myself.
