bugfix: Preserve unit behaviour when transferring assets to allies

[Stubbjax]

This change preserves unit behaviour when a player's assets are transferred to an ally player.

Transferred assets run through the onCapture logic, which tells them to idle in order to prevent undesirable circumstances like captured enemy objects continuing counterproductive tasks against the capturing player (e.g. we don't want a Dragon Tank to keep flaming our base when we hijack it). Some of these tasks are somehow preserved anyway, such as construction and capturing, while others are not, such as hacking, moving and attacking.

In the retail game, this idle-on-capture logic does not take ally asset transferal into consideration, in which case continued behaviour is always valid and desirable. A player will often want to give some of their units some final tasks before they surrender in order to give their ally a helping hand, such as moving workers to safety or attacking a target. Players especially always want their Hackers to keep on hacking. With this change, such tasks are now maintained as expected when transferred to an ally.
