Datepicker: In unstyled mode the minute decrement button keeps its css classes

[simplg]

Describe the bug

When using unstyled mode on the datepicker component, the css class in the decrement button for minutes (only) are still present while they are indeed removed from the other increment/decrement buttons (hour / seconds) which causes misalignment between the buttons.
