Add interaction type and gene claim category if not already in DB

[jsstevenson]

Currently, the base Importer class will raise an error if it encounters an interaction type or gene claim category that isn't already in the corresponding tables (see eg

dgidb-v5/server/lib/genome/importers/base.rb

Line 92 in 2c5d36a

def create_interaction_claim_type(interaction_claim, type)

)

We should (in separate issues) ensure that the normalization of the values going into those fields has satisfactory results -- but I don't think a normalized value should have to be manually added to any tables, so the constraints above should be removed, and if the value isn't already in the table, the importer should add it.

applicable to gene claim categories, for interaction claim types perhaps a rake task is best
