Title: Ensure primary index increment is set to nil

There was a bug when setting the increment value on the primary index that resulted in increment being equal to an empty string instead of nil.

```
opts[:increment] = nil
@primary_index[:increment] = opts[:increment].to_s || nil # @primary_index[:increment] => nil.to_s or ""
```
