Revert "svt: Use constructor feature for FilePicker and FolderPicker..."

It does not make a real sense to use constructor for implementations that act
as a trampoline; instead, we should do a constructor for the real
implementations that hide behind it.

This reverts commit 2fbb471567.
This reverts (part of) commit 58ea27124a.
