fixes #3597

PPM settings for external module:

PPM stream with internal RF set to OFF and external RF set to PPM with above settings - OK
All sticks at neutral except CH1 set to Min. Channel monitor confirms all channel 1 at 988us, channels 2 to 8 at 1500us. Notice all 8 channels correctly transmitted, timing as expected.

PPM OFF to PPM ON without glitches - - OK

LGTM on TX16S, TX12 MK2 and X9D+2019... prior to this PR there were seven pulses, with the first channel missing (when configured with defaults - 8CH)... looks like the first was merged into the second?

After this PR all eight are present and accounted for 🤭
