Aggregate Functions does not work with Indexed DB adapter

[flachica]

I tried calling functions store.max() with the adapter Indexed-db and always returns an empty value. To see that there is not an error in my source code I went to the test folder.

If we link the indexed-db adapter in the test file fail every test.

File: <lawnchair_repo>/test/plugin/aggregation.html

To test simply change line 11 with this code and open the file in browser

<!-- <script src="../../src/adapters/memory.js"></script> -->
<script src="../../src/adapters/indexed-db.js"></script>
