Even though our tests are written in a way that they shouldn't interfere
with each other, it may happen that one testrun writes content to a file
that upsets a different testrun. The resulting problems are often
difficult to diagnose.
To minimize the problem, let's add code that can reset the cards to a
defined state. This can be done using pySim-shell's export
feature. We can generate a backup from a known good state and then play
back the backup to reset files that have been changed. Files that didn't
change will not be written thanks to the conserve_write feature of
pySim-shell.
