Description

Error during running ContestEstimator for classes that have anonymous classes:

<StatsForClass(com.google.common.collect.TreeMultiset)> :
	canceled by timeout = false
	#methods = 61, 
	#methods started symbolic exploration = 61
	#methods with at least one TC = 8
	#methods with exceptions = 4
	#generated TC = 8
	#total coverage = 117/2161
	#fuzzed coverage = 117/2161
	#concolic coverage = 0/2161

As result ContestEstimator doesn't produce any test.

To Reproduce

1. Set 'guava' project in ContestEstimator.kt class, fuzzingRatio = 1.0, timeLimit = 60
2. Change file utbot-junit-contest/src/main/resources/classes/guava/list and leave only com.google.common.collect.TreeMultiset
3. Run ContestEstimator

Expected behavior

Generated test can be found in utbot-junit-contest/build/output

Actual behavior

No test generated.
