function EntityCacheTagsTestBase::testReferencedEntity

Tests cache tags presence and invalidation of the entity when referenced.

Tests the following cache tags:

• entity type view cache tag: "<entity type>_view"
• entity cache tag: "<entity type>:<entity ID>"
• entity type list cache tag: "<entity type>_list"
• referencing entity type view cache tag: "<referencing entity type>_view"
• referencing entity type cache tag: "<referencing entity type>:<referencing entity ID>"
