AutoTest: Qml file modifications might still get ignored

Steps to reproduce:

• open the test project (mixed_atp) used inside the plugin unit tests
• expand the Quick Tests node
• go through all named test cases and remove/comment out the name property to make them unnamed

Current result:

• if the qml file is not listed inside the project file (which is legit for Quick tests) it won't get moved to the unnamed Quick tests

Note: Rescan helps.
