Datasets table doesn't report backend for non-classification databases

[pansk]

I have one classification DB and several DBs of type "Other". The backend column reports "lmdb" for the classification DB, but is empty for all the other DBs.

I also tried to create a new one (all those DBs were created before upgrading), and even the new one don't report anything as backend.

Good point. I never got around to setting the backend for Generic datasets because LMDB is the only backend supported. And I'm actually finding it convenient at the moment because it gives me a way to distinguish Classification datasets from Generic ones. But you're right - we should display them as LMDB and find some other way to distinguish between dataset types.

@jmancewicz you were working on adding data extensions to the home page for sorting, right? Any update?

@lukeyeager, I just created a PR for it #1246
