Swap Ptolemaic Slinger & Javelineer

D3269 / 1649a8c221 made Mercenaries unable to gather. Ptolemies
Javelineers are mercs, so thy now had a non-gatherer starter unit,
putting them at a disadvantage.
This swaps the Merc javelineer with the slinger to correct for that.

Patch by: Nescio (for Stockfish0ad)
Differential Revision: https://code.wildfiregames.com/D3378
This was SVN commit r24649.
