Improve unit test coverage for SideMenuBar, UiBinding, Charts, Contacts, and REDebugCompiler (#4252)

Added new unit tests covering:
- SideMenuBar.MenuTransition
- UiBinding.BoundTableModel
- TimeChart
- PieChart
- ContactsModel
- REDebugCompiler
- CubicLineChart
- CombinedXYChart
- PushContent
- ChartComponent.ZoomTransition

These tests use the UITestBase infrastructure and TestCodenameOneImplementation.
