Successful and tests with exceptions are put into one unnamed region

[alisevych]

Description

There should be the following regions in the generated test class:
.Test suites for executable ... and sub-regions inside:
..SUCCESSFUL EXECUTIONS for method...
..ERROR SUITE for method...
..EXPLICITLY THROWN UNCHECKED EXCEPTIONS for method...
Now successful test and tests with exceptions are put into one unnamed region - when there are some generated by Fuzzing.

To Reproduce

Steps to reproduce the behavior:

1. IntelliJ IDEA 2022.1.4 is running with UTBot installed (https://github.com/UnitTestBot/UTBotJava/actions/runs/2955784591)
2. Check that Fuzzing is on
3. Open/clone UTBotJava project
4. Open utbot-sample/src/main/java/org/utbot/examples/objects/ObjectWithPrimitivesExample.java
5. Generate tests for createObject method
6. Open Structure toolbar for the generated test

Expected behavior

Generated tests are supposed to be distributed into 3 sub-regions:
. SUCCESSFUL EXECUTIONS for method...
. ERROR SUITE for method...
. EXPLICITLY THROWN UNCHECKED EXCEPTIONS for method...

This is the screenshot from the demo made on July 25:

Actual behavior

There are only two regions: unnamed and ERROR suite.
Successful test and one with IAE are put together into unnamed region.

Environment

Windows 10 Pro
IntelliJ IDEA 2022.1.4
JDK 11, language level 8

Additional context

Reproducing on other classes too - when there are tests generated by Fuzzing in the result test class.
