NPE from Fuzzing providers for static code block with File operations

**Description**

NPE from Fuzzing providers for static code block with File operations

**To Reproduce**

1. Run the 'utbot' project in IntelliJ Idea 2022.2.4 Ultimate
2. [Install plugin built from unit-test-bot/rc3102023 branch](https://github.com/UnitTestBot/UTBotJava/actions/runs/4448325159)
3. Set Fuzzing 100% in Settings -> Tools -> UnitTestBot
4. Generate tests for `read` method in the following code:

```java
public class SecurityCheck {
    public int read(A a)  {
        return 10;
    }
}

class A {
    static {
        new File("a.txt").renameTo(new File("b.txt"));
    }
}
```

**Expected behavior**

Tests are supposed to be generated.

**Actual behavior**

No tests are generated.
NPE is present in utbot-engine logs.

**Visual proofs (screenshots, logs, images)**
