Let's define an environment MINIDRIVER_PIN=1234 in order to be able
to reuse the tests with any cards.
usage:
(cmd) set MINIDRIVER_PIN=1234
When the PIN code is not defined, let's skip the tests since it may runs
the number of trials out of the max attempts.
Moreover, some cards may have many roles, but the tests are designed for
the ROLE_USER, so let's enforce only the ROLE_USER.
Fix: issue #2326
