IPA_Tests: fix matching of tr_provideEimPackageResult_ePRAndNotif

The template tr_provideEimPackageResult_ePRAndNotif got extended and
has now default parameters that break TC_proc_euicc_pkg_dwnld_exec_rollback,
so we must set euiccPackageResult to "?" to restore the original conditions
of the testcase.
