PluginException with TestGenerator.reformat

[alisevych]

Description

PluginException with TestGenerator.reformat is falling in IDEA when tests are generated.

To Reproduce

Steps to reproduce the behavior:

1. Open IntelliJ IDEA
2. Plugin is installed
3. Create a new IDEA project with JDK 8 (reproduced with Gradle projects and JDK 8/11)
4. Add a class like that

public class ListToStringExample {

    public void toStringList() {
        // Arrays.asList("a", "b", "c").toString();
        List<String> list = new ArrayList<>();
        list.add("a");
        list.add("b");
        list.add("c");
        list.toString();
        Random random = new Random();
        list.get(random.nextInt(list.size()));
    }

    public boolean rand(int a) {
        Random r = new Random();
        return r.nextInt() > a;
    }

}

Expected behavior

No exception is supposed to be thrown.

Actual behavior

com.intellij.diagnostic.PluginException is thrown with the following stacktrace:

[alisevych]

Reproduced again in Maven project with JDK 11 when test generation is run

[alisevych]

Doesn't reproduce last 2 weeks.

[dtim]

It seems that this bug is present again in main. To reproduce: generate any tests for a new class so that no Java test files for that class would be present in the test root (it is possible to just remove all data from the test root, or to create a fresh package with a class under test).

[amandelpie]

I obtained this bug for test generation, but all tests are generated well

[Vassiliy-Kudryashov]

Cannot reproduce it.
