1. example test uses auto detect flash size. we need to call
`detect_flash_size` before write flash
2. fix incorrect baudrate used: when using WROVER-Kits, it's likely that download with baudrate 921600
will fail. If we don't reset serial setting in decorator, 921600 will
become the default baudrate. This causes all the subsequent
communication fails
