* First construct a ProjectPart completely, then append it to the
  ProjectInfo. Doing it the other way around will lead to
  inconsistencies since some attributes of ProjectInfo are
  calculated/updated when a ProjectPart is appended. This has no effect
  on the current tests.

* Remove created *.user file when test finishes.

* Add comments describing what the tests do.

* Rename test methods to some more desribtive names.

When a second project was opened the snapshot was reset. That resulted
in all kinds of problems since from then on the code model effectively
was not aware of the files of the first project.

The regression was introduced by commit a0d6df7b.

Resetting the environment (after each *.cpp file) did not clear the
already seen files (m_included). Because of that the succeeding header
files were not parsed correctly - the environments of the mistakenly
already seen header files were not merged in.

Note that this change slow downs the parsing/indexing of files to its
original speed, as it was before the problematic commit (and it is in
2.7):
