Description

If the controller service was down and the schema was updated,
the schema will not be found, even though it exists just because it is not the latest version.
This fix searches for uncached schemas through the registry's subjects to figure out which version of the subject it was, even if it is not the latest schema.

This patch is for version 1.5.0
