'ByFuzzer' at the end of the test method generated by engine

Branch: andrey-t/summarization_in_contest_estimator

Description
Some test methods created by UTBot have suffix ByFuzzer even though it's generated by symbolic engine. Per @Markoutte we should just get rid of this suffix completely.

To Reproduce

Steps to reproduce the behavior:

1. Open utbot project
2. Set filters for contestestimator in org.utbot.contest.ContestEstimatorKt#main

       methodFilter = "com.google.common.collect.ReverseOrdering.*"
       projectFilter = listOf("guava-26.0")

3. Disable fuzzer: val fuzzingRatio = 0.0
4. Run contest estimator

Expected behavior

No tests named after fuzzer

Actual behavior
At least one of the test has ByFuzzer suffix

@Test
    public void testMaxByFuzzer() throws Exception  {
...

Note that a branch with summarization support in ContestEstimator was merged into main right now.

The problem is highly likely located in generateSummariesForTestsProducedBySymbolicExecutorWithoutSources method, I just copypasted a little more that required from Fuzzer.
