MicroPython and NimBLE must be on the same core, for synchronisation of the BLE ringbuf and the MicroPython scheduler. However, in the current IDF versions (3.3 and 4.0) there are issues (see e.g. #5489) with running NimBLE on core 1. This change - pinning both tasks to core 0 - makes it possible to reliably run the BLE multitests on esp32 boards.
