CodeChecker and ninja compatibility

[ChGen]

Describe the bug
There's a compatibility bug between ninja builder output and CodeCheckers, which leads to CodeCheckers crash.

To Reproduce
Steps to reproduce the behaviour:

1. Unpack source code. Reproduced with https://github.com/mysql/mysql-server/archive/refs/tags/mysql-cluster-8.0.39.tar.gz -o mysql.tgz
2. Run command 'cmake -GNinja path/to/cmake/file' to generate ninja build file.
3. Run ninja to generate compilation database. ninja -t compdb > ./compile_commands.json
4. Run CodeChecker analyze ./compile_commands.json -o ./result_tidy .... See the error. Interestingly, generating via cmake for this project works correctly.

Traceback (most recent call last):
  File "/usr/local/lib/python3.10/dist-packages/codechecker_common/cli.py", line 209, in main
    sys.exit(args.func(args))

    action = parse_options(entry,

    if gcc_command[0].endswith('ccache'):
IndexError: list index out of range

problematic json example:

{'analyzer_options': [], 'compiler_includes': [], 'compiler_standard': '', 'compilation_target': '', 'analyzer_type': -1, 'original_command': '', 'directory': '/root/mysql-server-mysql-cluster-8.0.39/bld', 'output': '', 'lang': None, 'arch': '', 'target': '', 'source': '', 'action_type': None} ; {'directory': '/root/mysql-server-mysql-cluster-8.0.39/bld', 'command': '', 'file': '/root/mysql-server-mysql-cluster-8.0.39/bld/CMakeFiles/show_boost_patches', 'output': 'show_boost_patches'}

As I understand, log_parser.py doesn't handle correctly the case when command item exist in json, but contains empty string, which leads to empty gcc_command and IndexError in the log_parser.py:662.

Expected behaviour
CodeChecker proceeds without crash.

Desktop (please complete the following information)

• OS: Ubuntu 22.04
• Python 3.10.12
• ninja 1.10.1
• CodeChecker 6.23.1

pip install -U pip setuptools
pip install codechecker 
...
cmake .. -GNinja
ninja -t compdb > ./compile_commands.json
CodeChecker analyze ./compile_commands.json -o ./result_tidy
