`Socket.connect` and `Files.readAllBytes` produce errors in Concrete execution

[alisevych]

Description

Socket.connect and Files.readAllBytes produce errors in Concrete execution

To Reproduce

1. Install Build from the unit-test-bot/rc112022 branch into IDEA 2022.2.3
2. Open UTBotJava project
3. Check File -> Settings are default: 95% Symbolic execution
4. Generate tests for the following class:

public class SecurityCheck {

    public int read(File path) throws IOException {
        byte[] bytes = Files.readAllBytes(path.toPath());
        return bytes.length;
    }

    public int connect(Socket socket) throws IOException {
        socket.connect(new InetSocketAddress("0.0.0.0", 22));
        return 0;
    }
}

Expected behavior

Tests are supposed to be generated without error reports.

Actual behavior

An error test is generated with information about errors in the concrete executor.

@SBOne-Kenobi
Also there is an unused import in the generated test:
import java.net.UnknownHostException;
Could you please check if it requires a separate issue?
