Fix breakpoints from Kotlin file placed in irrelevant class (KT-19429)

State that there're no locations in given file, if all locations for
line were filtered out because of wrong file name. Need this because
if we throw exception, other positions managers may return locations
without explicit check for file type or file name.

See PositionManagerImpl.java
