plparser: Fix return value from cancelled calls

As per the API documentation, and the code when it still used
g_simple_async_result_*, totem_pl_parser_parse_finish() should return a
TotemPlParserResult of TOTEM_PL_PARSER_RESULT_CANCELLED when parsing is
cancelled.

But the port to GTask changed that, as all the errors caught during
parsing would return -1 as the error code, which isn't a valid
TotemPlParserResult value.

As the only way for totem_pl_parser_parse_finish() to have a GError set
is for the call to be cancelled, catch that and correct the return
value.

Fixes: 45664037 ("plparse: Port from GSimpleAsyncResult to GTask")
Closes: #38
