calculateQueryCacheHash / calculateResultCacheHash with pendingJoinConditions

I've modified SoftDelete so that the preDqlSelect part is only applied when a specific param in the Manager is set. Currently this works like expected, but I've discovered a small problem, when I've enabled the QueryCache:

Since SoftDelete adds the "where is_deleted=0" as a pendingJoinCondition it isn't taken into account by the calculateXXXCacheHash function

I've made a small patch to Query/Abstract.php that takes the pendingCondition into account
