restore-delete : do not remove from tracker until note is deleted

trashed notes are still indexed.
bijiNoteObj: remove old func from header
note: implement is_trashed
noteObj.c : fix note_obj_is_trashed name

name was incomplete
controller: show search results according to trashed

now trash bin shows trashed notes.
standard view shows standard notes.

First, this allows to search inside Trash view.
Second, this obviously fixes one bug
where notes result appeared while viewing trash bin.
