`Execution configuration must not change between states` on `spoon` project

[tyuldashev]

Description

Some tests are not generated with error Execution configuration must not change between states on spoon-core-7 project

To Reproduce

Steps to reproduce the behavior:

1. Open utbot project
2. Open org.utbot.contest.ContestEstimatorKt file
3. Set filters on project and class:

        methodFilter = "spoon.pattern.internal.node.MapEntryNode.*"
        projectFilter = listOf(
            "spoon-core-7.0.0"
        )

4. Increase timeout if tests are not generated (val timeLimit = 300`)
5. Run ContestEstimator

Expected behavior

Tests are generated without errors

Actual behavior
Some tests are not generated due error:

    public void testGenerateTargets_errors3()
     {
        // Couldn't generate some tests. List of errors:
        // 
        // 1 occurrences of:
        // Execution configuration must not change between states
        
    }
