Fix ProjectListSpec when running multiple specs

DW.work_off defaults to 100 jobs, but that isn't always a large
enough count if there is a backlog. When ProjectListSpec was run
with enough other specs that didn't complete their work, the backlog
was growing to more than 100, causing last_observation not to get
updated in this test.

Deleting the DJ backlog before each test fixes this issue, allowing
the subspecies test to pass.
Limit faked GuidePhoto description to 255 chars

Avoids this problem:

  Failure/Error: gp = GuidePhoto.make!(:guide_taxon => gt)
  ActiveRecord::StatementInvalid:
    PG::Error: ERROR:  value too long for type character varying(255)
    : INSERT INTO "guide_photos" ("created_at", "description", "guide_taxon_id", "photo_id", "position", "title", "updated_at") VALUES ($1, $2, $3, $4, $5, $6, $7) RETURNING "id"
Fix Observation spec failure in bulk test run

* Use time_observed_at_in_zone instead of Time.use_zone to avoid
  weird interaction with ObservationsController tests
* Use eq(14) instead of be(14) for equality test
