Fix Asterix Installer Test Cases Many tests started to fail in installer after being disabled for a long time. This change fixes the following: 1. asterix-installer: external library tests. 2. asterix-installer: recovery: query-after-restart.
Enabled Feed Tests and Added External Library tests Feed tests had been switched off for a while due to having too many sporadic failures. Now, we are switching them back on. In addition, a new set of tests have been added to test that external library works as expected.
