Add equality and empty tests for first_contentful_paint

ksakamoto discovered that our PageLoadTiming code is missing
equality/empty tests for the first_contentful_paint field.

This means that when FCP is different from FP, and no subsequent
metrics are logged for a given page, FCP may erroneously not get
logged for that page.
