Extender is failing to generate any test cases from test generators output

Describe the bug

When running on https://github.com/shashirajraja/onlinebookstore/ extender fails to generate any test cases:

* CTD interaction level: 1
* Total number of classes: 13
* Targeting 10 classes
* Skipping 3 classes with only private methods
* Created a total of 8 test combinations for 8 target methods of 10 target classes

Attachments

To help us diagnose the failure, please add these attachments to the issue, as appropriate:

• The toml file containing the configuration information used
• The log file created by running the CLI with the --verbose and --log-level INFO options
• If possible, a zip file containing the application classes, and the file specified as app_classpath_file option in the toml file together with the library dependencies listed in the file
• If the failure occurred for the generate command, please attach the following files if they were created during the failing run:
  • The CTD test plan JSON file (<app-name>_ctd_models_and_test_plans.json)
  • The building-block test sequences JSON files (<app-name>_EvoSuiteTestGenerator_bb_test_sequences.json and/or <app-name>_RandoopTestGenerator_bb_test_sequences.json)
• If the failure occurred for the execute command, please attach the zip file of the directory containing the generated test JUnit test cases
