lib-storage: Changed separator between session_id_prefix and unique part to be ':'

Although '-' wasn't used by default either, it's much more likely that
custom session IDs might contain it. ':' is hopefully less likely to be used.
This allows log parsers that actually want to find out the original session's
all log lines to cut out everything after the initial ':'.
