Filter Summary test

[adriamurphy]

Filter summary test for results.cy.js will fail if hierarchy is the first first in the list. This is because hierarchy facets don't get added to the filter summary. (I'm surprised this hasn't come up sooner!) We need some way (on the below lines) to determine if the first facet is hierarchy and if so, select the second one instead.
