Minion generated by "Choose One" cards have no PlayOptions

[yangyuan]

When testing #9, I noticed that Minion generated by "Choose One" cards have no valid "PlayOptions" after being summoned.

For example, after using "Keeper of the Grove"(EX1_166), the NetworkOptions only contains the original sub card options ("EX1_166a", "EX1_166b"). However, it should contain the possible attack options.

The NetworkOptions are provided by the server, so this should be a server bug. There is no way to solve that from Hearthrock side (unless totally re-design the "PlayOptions" feature) and only happen occasionally.

Create this issue just in case someone notices this.
