Test case

There's a bug in Safari 11.1 when you try to add a record with binary data (Uint8Array) into an indexedDB store having an autoIncrement key.

The triggered error is "UnknownError: An internal error was encountered in the Indexed Database server", and then the whole database is broken and can't be reopened/reused.

This issue neither happens if you have binary data and a store without autoIncrement, nor non-binary data and a store with autoIncrement. Only having both is an issue.

Breaks (at least) on Safari Version 11.1 (13605. on macOS High Sierra 10.13.4.
