* fix bug where savesettings did not honor local settings variables
* don't create lib/flows on read; It's already created in localfilesystem.init and in saveLibraryEntry -
so removed call to promiseDir, and added a return of [] if accessing a folder which did not exist.
This is important because else when settings.readOnly is true, it still creates folders.
* Fix a CI failure where path passed to getLibraryEntry is empty;
treat this case as meaning it was wanting a folder, and return empty if the folder dioes not exist
* Add a test for getLibraryEntry( type, '/' ) as called by node-red
* change newsettings to camelCase newSettings
