displaCy: Avoid increasing levels for identical arcs (#10639)

Browse Source 
* Test for arc levels for identical arcs

Also moves the test in order with the other numbered tests.

* displaCy: filter identical arcs

Avoid increased levels due to identical arcs by first
filtering any identical arcs.

* Sort keys before filtering

Manual entry with keys out of order would previously become
different tuples and therefore not filtered correctly.
