Title: CORE: fixed implementation of delete password method

- delete password only when reserved by registrar
- do not delete password when reserved by attribute or not reserved at all

Previous wrong behavior

- if not reserved by both attribute and registrar -> delete password
- if reserved only by attribute -> throw exception
- if reserved only by registrar or both -> do nothing
