jQAssistant finds non-existing and nameless files

[obfischer]

While working one jQAssistant/jqassistant#353 I wrote a IT to see how many files jQA will find in a testbed for jQAssistant/jqassistant#353. The testbed is a directory with eight files. But the database created by jQA contains 10 nodes labeled with :File. Interestingly the aditional two files does not have a name.

To reproduce this issue open the class ComplexTestsForMavenSupportIT and enable the test called shouldFind8Files(). This test was added on the branch 1.1. It can be found on master after merging 1.1 to master.
