[test] Added simple tu_collector test.

[balazske]

The test analyzes a project and collects the files with tu_collector. Then these files are analyzed again in a new directory.

The goal is that the first step of analysis is not needed, tu_collector should generate a compiler_info.json file. Currently it is really not needed but if the compiler_info.json would be included then yes. Additionally, a next step is to make the test work with "failed" zip files too that are created during the analysis.
