[RAM] Rule event log list - incorrect result filtering by message and outcome at the same time

Source comment: #142645 (comment)

In the rule event log list, when filtering by event log message and event log outcome at the same time, the result is incorrect, this is because we forgot a parenthesis in the query:

i.e. the query is:
message: "test" OR error.message: "test" and event.outcome: failure
but should be:
(message: "test" OR error.message: "test") and event.outcome: failure
