parse: Fix transfer annotations for parse_launch functions.

gst_parse_launchv, gst_parse_launchv_full and gst_parse_launch_full
all return floating refs, the same as gst_parse_launch, which just
calls gst_parse_launch_full internally anyway.

Add a unit test assertion to check it's true.

Spotted by nemequ on IRC.
