Remove unnecessary expectation

This was originally in to ensure the page was correct when hitting
"/ingest" directly.  It's no longer necessary since we're getting to
the ingest form via links now.
Refactor ingest spec

- Rewrites ingest spec to test in smaller "chunks"
- Simplifies most of ingest-related specs to avoid JS requirement
- Fixes some pending tests to actually test the catalog view now that
  it's been implemented
