[wendi616]

As the title, user can change the some of atrributes of the suite or case , in that case, if we try to filter with the modifier value by -t or -i, the pabot will get nothing, but it works in robot scenario.

Pabot Version: 4.0.4
Robot Version: 7.0.1

`$ robot --prerunmodifier Modifier.py -i tag2 .
