Extend timeout in testSearchContextIsCleanedUpAfterPageTimeoutForAggregationQueries (#132674)

Fix #132619

or try to, anyway. It looks like the cursor is sometimes already closed
before we assert that it was created. Keep it alive a little longer (1s
instead of 0.5s) so the assertion that the cursor is alive has a higher
chance of succeeding.
