abstract-leveldown tests aren't all passing anymore

[max-mapper]

right now the tests don't pass in latest chrome. Not sure if it was something in chrome, idb-wrapper, or abstract-leveldown that changed but if someone has some time to dig in and try and make the tests pass it would be much appreciated

I max, I think you bumped abstract-leveldown too far, and the module is now broken. From 0.12 to 2.4 there are plenty of breaking changes: e693249.

I hope to have a look asap.

0.12 behavior differs from 2.4
For example, it rebels against empty values.
Quite an annoyance.

@maxogden @mcollina I'm actively working on this right now and I'd love to see this repository moved to the level org. @juliangruber and @vweevers are also very active.

@gritzko We want to take stuff like that out of abstract-leveldown in a new major version. abstract-leveldown should basically assume nothing about serialization of different *downs. We also want to clean up browser specific assumptions in the code.
