Pabot is not handling error cause by the --command option

[RasmusGOlsen]

If calling Pabot with the option --command mycmd robot --end-command and mycmd fails, i.e. Robot fails to start the test case, Pabot will not handle this. I would expect the XML to be generated with the reason that the test case failed to start.

# file: example.robot
*** Test Cases ***
Test A
    Log    Running ${TEST NAME}

Test B
    Log    Running ${TEST NAME}

$ pabot --splitleveltest --command mycmd robot --end-command example.robot
