When an accessible-slick slider becomes 'unslicked' (via the responsive settings or via jQuery), the role and aria-label that are appended upon 'slicking' persist. This makes for excess attributes that a screen reader will read out when the carousel no longer exists. The role and aria-label should be removed upon destroying the slider.

Minimal demo showing persisting attributes:
