Tests refactoring: select element

[alla-blinkova]

Should be done AFTER #4986 and #4987 are completed.
Tests should be added to cover features:

• aria-label: string
• disableRipple: boolean
• hideSingleSelectionIndicator: boolean
• placeholder: string
• required: boolean

Existing tests should be updated to use the new implementation of Select element instead of MaterialSelector and NativeSelector.

• Review Paginator element and consider replacement Dropdown to Select
