[ALS-5505] Update to add 'and' to scanner filter when more than one filter condition exists

[srpiatt]

When a user logs into SWB as a researcher the API returns a validation error.

In my local, this returns an error message (although id doesn't seem to display a message in prod). Regardless, because of this the env data does not successfully refresh without a manual page reload.

The cause of the validation error is the applied since and createdBy filters. When multiple filters were applied, it was sending the filter expression as #c = :c #u = :u instead of #c = :c and #u = :u, which is required for scanner operations.
