UTBot shutdown then LLVM fail with error

[ladisgin]

steps to reproduce on release tag 1.0.93

1. Generate tests for calc.c
2. Add into CMakeLists add_executable(c-example main.c) and try generate for main.c
3. Add line CMakeLists target_link_libraries(c-example lib src) and try generate for main.c

workaround:

• Delete build directory from project and tmp directory from utbot_distr.
• Write correct CMakeLists.txt
• Try generate again
