Display turns on briefly without pressing button #762

Most common on the RTK Facet/Facet L-Band, device will turn on briefly showing the SparkFun logo before turning off again.

Cause: This is due to leakage current on the BAS16J diode used on the circuit used to power on/off the device, and varies based on the tolerance of the BAS16J diode.

Display now activates after a full power-on-button-hold test is completed.
