Removes use of #handle_asynchronously, which we need to do elsewhere. Fixes:
BulkInvoiceService#start_pdf_job starts a background process to create a pdf with multiple invoices
Failure/Error:
expect do
service.start_pdf_job [1, 2]
end.to enqueue_job Delayed::PerformableMethod
expected to enqueue exactly 1 jobs, but enqueued 0

Patches Paranoia gem to fix a conflict with transactions in Rspec: https://github.com/rubysherpas/paranoia/issues/274
Example error:
```
Failure/Error: order.line_items.first.variant.tap(&:delete)
NoMethodError:
undefined method `state' for #<ActiveRecord::ConnectionAdapters::NullTransaction:0x0000564117dddd18>
```
The logic of #includes has changed slightly in Rails 4.2 and now usually needs the #references method as well.

Recent changes to the way count_on_hand is summed in Spree::Stock::Quantifier mean the old method here will not work. Error:
```
2) Spree::Variant#in_stock? when stock_items are not backorderable when stock_items out of stock return false if stock_items out of stock
Failure/Error: expect(variant.in_stock?).to be_falsy

The enterprise id returned by these json endpoints was being returned in *unicode* format, so where Angular was expecting a simple integer it was instead getting strings like: "\u0017"
For some reason when using `render text:` instead of `render json:` for this response, the status code being returned was 200 instead of the clearly explicitly defined 422 (:unprocessable_entity). I absolutely have no idea why!
This route checks if an enterprise permalink is taken or not. Allowing the route to be accessed via Javascript without strict CSRF protection is reasonable. Fixes the following errors:
ActionController::InvalidCrossOriginRequest: Security warning: an embedded <script> tag on another site requested protected JavaScript. If you know what you're doing, go ahead and disable forgery protection on this action to permit cross-origin JavaScript embedding.
