We have 3 test cases for this currently:
1) "qcow2->raw"
1.1) VIR_STORAGE_FILE_QCOW2 as top level format
1.2) VIR_STORAGE_FILE_AUTO as top level format
2) "wrap->qcow2->raw" whith just VIR_STORAGE_FILE_QCOW2
This patch adds also testing of VIR_STORAGE_FILE_AUTO for case 2) and
removes both 1) subcases as they are being actually tested as part of
2).
