Migration fails for 5.1(.7?)

[nfstern]

Actually, I fixed it manually, but the maintainer of the gem may like to look into this.
in the eav_migration.rb, add
[<%= ActiveRecord::Migration.current_version %>]
to the end of line 1

Remove line 13 (if the current_version is 5.x or greater?) which is causing a duplicate index issue. Rails 5.1(.7?) is creating the index as part of the relationship with a name. The same name gets used for line 14 which causes a duplicate index name issue and the migration to fail.

13. add_index :<%= table_name %>, :<%= model_association_name %>_id
14. add_index :<%= table_name %>, :entry_key
