#465: The 'active_originals_count_by_project_id' cache race condition
--------------------+-----------------

Component:  Cache   |    Version:
 Keywords:          |
--------------------+-----------------
 The 'active_originals_count_by_project_id' cache is set within
 `GP_Original::count_by_project_id()` and only deleted at the start of the
 `GP_Original::import_for_project()` method.

 This results in the following condition where the cache group is out of
 date:
 - Process 1 starts import, clears cache
 - Process 2 calls `GP_Original::count_by_project_id()`, caches the current
 count
 - Process 1 continues importing..
 - Process 1 finishes import.
 - Process X calls  `GP_Original::count_by_project_id()` and gets a stale
 cache.
