Added unit test for notes with tags

Added NotesControllerTest#test_note_with_tags unit test for testing cases when note has tags and comment (description). Internally, new note is created with comment (description) and several tags and then rendered in sidebar. Existence of appropriate HTML tags for notes, comment (description) and tags is checked.
