[BUG] Sometimes CLion integration tests fail in CI

[vol0n]

Description
Sometimes CLion integration tests fail in workflow run.

To Reproduce
Could not reproduce it locally on my machine. To catch it in ci, launch the job Build UTBot and Run Integration Tests several times until clion tests fail.

Expected behavior
All tests must pass.

Actual behavior
Line tests fail with timeout exception. When plugin sends request to get project targets, server does not respond, and timeout exception is thrown.
