filter_ems_data() - filter dates not working as expected

[KarHarker]

Issue found when using filter_ems_data() with specific date constraints - documentation here: https://github.com/bcgov/shinyrems/issues/132

From first glance: I think the issue is that the COLLECTION_START has h:m:s and to_date does not so the default is 00:00:00 which occurs before COLLECTION_START even if the y:m:d is the same
