Invalid use of reject causing real error to be swallowed

The "onabort" handler of indexedDB transaction
https://github.com/localForage/localForage/blob/b6a47080ba946e3ca659c1d7358a04521440e5cf/src/drivers/indexeddb.js#L668-L671

is throwing following error
```
Uncaught Error: The error you provided does not contain a stack trace.
at parseError (index.js:2370)
at getStackFrames (index.js:2263)
at crashWithFrames (index.js:1927)
at index.js:1945
at rejectionHandler (index.js:2041)
```

when getting DOMException
```
DOMException
code: 22
message: ""
name: "QuotaExceededError"
__proto__: DOMException
```

Start in src/drivers/indexeddb.js at the onabort handler around lines 668-671 and reproduce the QuotaExceededError DOMException described in the issue. Trace how the rejection is handled and confirm that the real IndexedDB error is preserved rather than swallowed or replaced by the missing-stack-trace error. Done means the original error remains observable when the transaction aborts.
