C++: Fix 'already seen files' when indexing

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):
