YAML filter does not tolerate empty list items

Feeding the YAML filter with a simple YAML list such as:

- one
- two
-
- three
- four

Results in:

net.sf.okapi.filters.yaml.parser.ParseException: Encountered unexpected token: "- " <DASH>
    at line 4, column 1.

Was expecting one of:

    "BLOCK_MAPPING_START"
    "BLOCK_SEQUENCE_START"
    "["
    "\"\""
    "\'\'"
    "{"
    <ALIAS>
    <ANCHOR>
    <DOUBLE_QUOTED_FIRST>
    <FOLDED_SCALAR_START>
    <LITERAL_SCALAR_START>
    <PLAIN_SCALAR>
    <SINGLE_QUOTED_FIRST>
    <TAG>
    <TAG_DIRECTIVE>
