Post-game analysis on server returns multiple winning hands on high-card result

[monicanagent]

When a player has a high-card hand result as the highest ranking winning hand, multiple hands appear for that player in the contract's post-game analysis.

A similar issue appeared in the client-side analyzer.

Although this doesn't appear to cause an issue with winnings distribution, it should nevertheless be limited to a single result.

Updated in commit 86d03b0

As with the client-side analyzer, the hand scoring mechanism in the smart contract interface grouped highest-ranking hands together in order to accommodate ties (more than one winner). For some hands, however, such as high cards, the highest hand score would appear in multiple permutations for the same player and therefore be repeated.

Hands are now filtered so that only one highest ranking hand is stored per player if more than one appears.
