Plugin UI. UnsupportedOperationException is thrown when new test source root creation is chosen

[alisevych]

Description

Plugin UI. Test source root dropdown is expanded. Option to create a new test root is selected. But options list is not closed.

To Reproduce

Steps to reproduce the behavior:

1. IntelliJ IDEA 2022.1.4 is opened with a new version of UTBot plugin installed.
2. Create a Maven / IntelliJ project
3. Add a class to it with a public method.
4. Open UTBot test generation dialog.
5. Expand Test source root dropdown. Select second option with "utbot_tests" to be created.

Expected behavior

Dropdown options list should be closed.

Actual behavior

Dropdown options list stays expanded - until a click on some other element is performed.
UnsupportedOperationException is thrown
