Modify `findNotes()` to use V16 `searchNotes()` function

[viciousAegis]

Modify SearchNotes to be able to use both legacy and V16 functions

Pull Request template

Purpose / Description

Add support for using new backend method searchNotes()

Approach

By checking the schema version, the newer function is used on using V16. The newer searchNotes() function includes a parameter for sorting, which is not supported in legacy.

findNotes() function is modified in Collection so that V16 can be used when enabled

How Has This Been Tested?

On my phone by enabling V16 backend in settings.

As a side note, I'd appreciate if you could remove part of the template that you don't fill, just so that I know what not to read and what information is relevant. Or ideally, fill it, e.g. to note that you can't test it in practice due to use of V16
