Non-server data-tables component not respecting 'default-sort' table option

[ajm5774]

Online reproduce

https://jsfiddle.net/eyn2x0rf/

Expected Behavior

Non-server table defaultSort should apply sort when table is created

Current Behavior

Non-server table defaultSort doesn't seem to do anything

Steps to Reproduce

1. Create non-server table with table id and name columns. Set default sort to name descending
2. Populated table with data with id and name where the name is not already sorted in descending order.
3. When the table is rendered, the name column will show as sorting in descending order, but it will not actually be sorted.

Detailed Description

Non-server table default-sort should apply sort when table is created.
When the table is created, we just need to call "handleSort" in DataTables.vue if a tableProps.defaultSort is provided.
