Import/Export not working and Read Transactions on Read Replicas failing

Fixes an issue with the Import/Export failing with Object Ref errors because the CurrentContext User was null #

Description

If the number of items to export was above 250 it would fail. An import would fail with a bunch of Object Ref Errors, even when importing the same exact file that was previously exported.

I had to set the HttpContext before setting the HccRequestContext. Also, when the HttpContext.Current was null it was always returning a new HccRequestContext even if _current was set.

In addition there was a race condition with Order Transactions when using scale out read replicas. If the read replica did not replicate fast enough the order transaction was never recognized and the order workflows would fail. I made sure that when reading order transactions that it always reads from the Main Instance instead of a read replica.

How Has This Been Tested?

I built my changes and deployed to my development test site. This site was not able to import or export. After applying my changes I was able to import and export.
