[nrf fromtree] tests: boards: nrf: qdec: modify QDEC tests to match new api

Overflow errorcode is now correctly detected when expected.
Subsequent sensor_channel_get() yield the same values, so
the check can be no longer ignored.
Added a sensor_sample_fetch() where missing for correct
sensor_channel_get() calls.
