Skip IndexedDB cleanup on Safari 14

[schmidt-sebastian]

This PR changes our IndexedDB shutdown to skip all remaining work items on Safari 14. It is believed that writing to IndexedDB during unload can trigger a bug on Safari that prevents IndexedDB from loading during the next page load.

Fixes #4076
