This set of fixes mainly address the issues where the JE backend does not handle attributes with options and subtypes correctly when they are being indexed. 
With this fix:
- All values of an indexed attribute type will be indexed correctly on modifies, adds, and deletes. 
- Updates to subordinate types will now update the superior type if its indexed. 
- Adding and deleting superior attribute types that are not allowed by any object classes (ie. name) will be correctly handled
- Deleting all values from an attribute with no options will no longer delete the values from the same attribute but with options.
