Cover summary builders with unit tests

Description

We need to cover SimpleCommentBuilder.kt, SimpleNameBuilder.kt, and SimpleClusterBuilder.kt with unit tests to capture the current behavior and make it easier to catch issues in the future.

I will try to do it using UTBot and on my own as well.

@sergeypospelov

UTBot couldn't generate any tests for SimpleCommentBuilder.kt.
Environment:

JDK version: Amazon Coretto 1.8

UTBot version: 2022.7-beta

IDE version: IntelliJ Community 2022.1.3

Build #IC-221.5921.22, built on June 21, 2022
Runtime version: 11.0.15+10-b2043.56 amd64
VM: OpenJDK 64-Bit Server VM by JetBrains s.r.o.

It shows same error report for several methods:

    ///region Errors report for genWarnNotification
    
    public void testGenWarnNotification_errors()
     {
        // Couldn't generate some tests. List of errors:
        // 
        // 1 occurrences of:
        /* class org.utbot.framework.plugin.api.UtCompositeModel cannot be cast to class org.utbot.framework.plugin.api.UtModel (org.utbot.framework.plugin.api.UtCompositeModel is
        in unnamed module of loader java.net.URLClassLoader @6abba1ec; org.utbot.framework.plugin.api.UtModel is in
        unnamed module of loader com.intellij.ide.plugins.cl.PluginClassLoader @4e9c8dd5) */
        
    }

@sergeypospelov could you please help with it? should I create an issue for it?

UTBot also failed to generate tests for SimpleNameBuilder.kt
Error report:

    ///region Errors report for conditionStep

    public void testConditionStep_errors() {
        // Couldn't generate some tests. List of errors:
        // 
        // 6 occurrences of:
        // Default concrete execution failed

        // 4 occurrences of:

    }

Unfortunately, it's impossible to use UtBot on our project with UtSettings.useConcreteExecution set to true. It's our internal problem and is quite complex. Looks like setting this option to false might help. It can be found in UtSettings.kt.
