Description
Fuzzing generation for org.utbot.examples.recursion.Recursion#vertexSum causes errors.

It seems specific to Gradle projects and reproducible not only in UTBot project.

To Reproduce

  1. Install UnitTestBot plugin built from main in IntelliJ IDEA
  2. Open UTBot project
  3. In settings set Fuzzing = 100%
  4. Generate tests for org.utbot.examples.recursion.Recursion#vertexSum

Expected behavior
Tests are generated.

Actual behavior
One error test is generated:

    public void testVertexSum_errors() {
        // Couldn't generate some tests. List of errors:
        // 
        // 1 occurrences of:
        // org.mockito.MockedConstruction$Context

    }

Screenshots, logs
