fix(database): using empty objects instead of empty arrays for date filtering

[braumye]

• The DateFilter class was modified to accept an object as a value in addition to string, bool, and array.
• The tests for CompoundFilter and DateFilter were updated to use objects instead of empty arrays for the past_week, past_month, past_year, next_week, next_month, next_year, and this_week properties in the date array. The tests were also updated to use assertEquals instead of assertSame for the expected and actual arrays.
