[BUG] `:modules:autotagging-commons:common:` tests can't be executed in the same JVM

Describe the bug

We were seeing test failures like the one below in our CI pipelines at times.

After looking into that we found that there are two tests - AutoTaggingRegistryTests and FeatureTypeTests that are calling AutoTaggingRegistry.registerFeatureType with a FeatureType that has name TEST_FEATURE_TYPE. And when those two tests are executed in the same JVM this problem happens
