Fix Sentinel reconnect test following ACL change (#10480)

Browse Source 
Replace condition with wait_for_condition On "Verify sentinel that restarted 
failed to reconnect master after ACL change"

The reason we reach it, is because the test is fast enough to modify ACL and
test sentinel connection status with the server - before its scheduled operation
got the chance to update connection status with the server:
```
/* Perform scheduled operations for the specified Redis instance. */
void sentinelHandleRedisInstance(sentinelRedisInstance *ri) {
    /* ========== MONITORING HALF ============ */
    /* Every kind of instance */
    sentinelReconnectInstance(ri);
```
