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>"
