List of available channels not updated when Morse Decoder or Demod Analyzer features are added

[f4exb]

When you add either a Morse Decoer or Demod Analyzer feature to a setup where available channels are present (e.g SSB Demod, WDSP receiver) these channels do not appear in the selection combo (remains empty) and thus cannot be selected. You have to add another channel so that the refresh process is triggered by the AvailableChannelOrFeatureHandler::channelsOrFeaturesChanged signal.

What I don't understand is that according to this line of code: https://github.com/f4exb/sdrangel/blob/master/plugins/feature/morsedecoder/morsedecoder.cpp#L72 this should work...

Maybe something has changed more recently and the GUI is created after the main handler and thus cannot be notified.

Edit: yes forcing the re sending of the MsgReportChannels message at the end of the GUI constructor fixes the issue.
