Maxime Lamothe-Brassard 25d3a5a893 Remove "condition" from global rule.
The condition field in this rule was in the global section which overwrote the condition in sub-rules and generated FPs. For example, once Sigma read the rule, the bottom sub-rule's "condition" was overwritten with "1 of them".
