Currently, if you have a raft, you don't get a skirt printed - skirt is disabled, and so the settings are ignored.
There are a couple of things that you can do to prime the head before the print starts. Firstly, as it nears the printing temperature, turn the extruder gear by hand, to force some plastic through the nozzle.

G1 Z15.0 F{travel_speed} ;move the platform down 15mm
G92 E0 ;zero the extruded length
G1 F60 E6 ;extrude 6mm of feed stock
M1 P2000 ;pause 2s
G92 E0 ;zero the extruded length again
G1 F{travel_speed}
