packrat mode is not being activated after cloning and packrat::restart()

Hi

I have Rstudio projects that are under packrat control with private libraries. When I clone these projects from Github in RStudio, packrat is being installed and the R session restarted, however packrat mode seems not to be turned on. I then have to run packrat::restore() and manually restart the R session to activate packrat mode.

I made an example https://github.com/burlab/packrat_restore_test which also shows this behaviour on all systems (Win and OSX) systems tested. The same behavour also occured when using the current development version of packrat.

Is there something I am missing out to automatically activate packrat mode after cloning or opening the R project that has been under packrat control, but with no installed packages?

Thank you for your time!

Start with the linked packrat_restore_test reproduction and the bootstrap output showing packrat installation, restoration, and restart after cloning in RStudio. Compare that behavior with packrat::restore(restart = TRUE) and verify the result on the reported Windows and macOS setups. Done means a cloned or opened project automatically enters packrat mode without a manual restore and restart.
