Autogenerated Flux code is different style from editor style

[nathanielc]

If you use the query builder to construct a query and then switch to the script editor the Flux code is placed into the text box.

This "generated" code uses 2 spaces for tabs, where as if you type a tab in the editor it uses 4 spaces. This makes editing the generating code cumbersome as you have to first realign all the generated code.
