2nd analysis fails when source file has been removed
Hi,

I tried to analyse https://github.com/flok99/Baislicka-2.0

First time I did on 2d7dc07dbfa0f86b2dbce897867bb4e3bc679ca7 (git hash):
CodeChecker check -b 'make -f mak' -o ~/results/ && CodeChecker store ~/results -n chess

Then I ran the following on 8a5fa3e50b2a96628fcda71b0c8d18a92d8730db:
CodeChecker check -b 'make -f mak' -o ~/results/ && CodeChecker store ~/results -n chess

which resulted in:

(CodeChecker venv) [sa@clang src]$ CodeChecker check -b 'make -f mak' -o ~/results/ 2>&1 | tee ~/0002-chess.log
