Don't add duplicate patterns all the time in EntityRuler (fix #8216) (#8246)
* Don't add duplicate patterns (fix #8216)

* Refactor EntityRuler init

This simplifies the EntityRuler init code. This is helpful as prep for
allowing the EntityRuler to reset itself.

* Make EntityRuler.clear reset matchers

Includes a new test for this.

* Tidy PhraseMatcher instantiation

Since the attr can be None safely now, the guard if is no longer
required here.

Also renamed the `_validate` attr. Maybe it's not needed?

* Fix NER test

* Add test to make sure patterns aren't increasing

* Move test to regression tests
