My shiny app and tests are setup as described in #359

It appears that this is a result of including a .Rprofile file in my app directory (see #359) that includes the following:

source("../renv/activate.R")
renv::restore(lockfile="../renv.lock")

If I comment-out the lines in the ./app/.Rprofile file, then the tests pass.

So, @gadenbuie I'm not sure what to do. Including ./app/.Rprofile allows the Github Action to succeed, but then my local testing with shinytest2::test_app('app') fails.

I'm closing this issue, since it should be fixed via #362
