Issue with different badge slugs

[josmas]

The manual migration of badge info from badgekit to badgr resulted in some of the badge class slugs being different (data-curation != data_curation), and this is problematic for the client.

The bin folder has a script to migrate instance data, but the badge class data had previously been added manually. Automating badge info should take care of this issue (or as a quick fix, overriding the manual data in badges_only.local.sqlite would also be a good fix for now.

note: This is only reproducible from the badgr-dev branch, which I haven't pushed up yet!

For instance the two following url produce different results (0 and 1):

this is on review #211. No more work needed for now.
