[bugfix] Use background context instead of request context for async …

…processing (#888)

Fixes an issue where async processing was not completing correctly.

In particular this applies to side effects of domain blocks: while the domain block was being entered and enforced correctly, side effects like deleting accounts and updating the instance entry for the blocked instance were not. This fixes that :)
