Correct test descriptions for fuzzing

[alisevych]

Description

Fuzzing test descriptions should be easily understood by user.
Text "mutated from 0" is a bit confusing because users know about fuzzing mechanisms very rarely.
Need to consider a better way to inform the user why the particular value is used.

Expected behavior

Remove unneeded information from test description - it is required for the test run report and thus should be easily read.

Environment

IntelliJ IDEA 2022.1.4
JDK 8 / 11

Potential alternatives

Probably add information that the value is random to the Java doc.

Context

For example:
utbot-sample/src/main/java/org/utbot/examples/recursion/Recursion.java
methods: factorial, fib

    @DisplayName("fib: n = 1024 (mutated from 0)")

    @DisplayName("factorial: n = 134217728 (mutated from 0) -> throw StackOverflowError")

Do you agree with this change?

[onewhl]

I like that @Markoutte added information about real values, it's very useful!
And I agree with @alisevych - "mutated from" could make a user feel confused. In general, users might be not familiar with fuzzing/symbolic execution terms, so let's skip this information in display names.

Probably I could move this information to the javadoc a little bit later.

I have a question: is it a new behavior added some days ago or old? I didn't faced with this example yet

@amandelpie it's there since #713. I wanted to show that some values were somehow (randomly at the moment) generated from another values. Now, numbers and strings are mutated. Also, mutation mechanism works for regexes, but it just regenerates values from a regex pattern.

@Markoutte looks like I need to pass it to you
