test(checkbox) add initial tests (#2551)

* test(checkbox): Add initial test for checkbox

* test(checkbox): Add test_checkbox_should_have_default_text_when_created

* test(checkbox): Add test_checkbox_should_return_dinamically_allocated_text

* test(checkbox): Add initial tests for static text

Tests are failing tho

* test(arc): Rename bugfix test to arc

Also adds reference to issue in a comment

* test(checkbox): Tests for static text passes

* test(checkbox): Remove test for memory freeing when static text is refreshed

NULL isn't a valid parameter in lv_checkbox_set_text_static
