Requirements
A number of NeoPixel LEDS, and enable NEOPIXEL_STARTUP_TEST
Description
Currently the RGB test at startup only displays Red and Green, Blue is missing.
The cause, Blue is being setup but is immediately being followed by setting a new colour;
The setting a new colour is part of the LED_USER_PRESET_STARTUP block. it either sets the neopixels to the preset colour, or all neopixels off. In either case BLUE is overridden.
Added a simple delay so blue can be seen.
Benefits
NEOPIXEL_STARTUP_TEST works as expected.
