CodeChecker analyze does not show analysis errors when it only re-analysis files
Even if there was error in the analysis, it is not shown properly if the report directory was existing when
analyze is called.
We expect the following output
~~~~~~~~~~
Total compilation commands: 12
[19:37] - Successfully analyzed
[19:37] -   clangsa: 5
[19:37] -   clang-tidy: 6
[19:37] - Failed to analyze
[19:37] -   clangsa: 1
~~~~~~~~~~

however we got
~~~~~~~~~~
19:29] - Total compilation commands: 12
[19:29] - Reanalyzed compilation commands: 12
