Previous station name retained when current name is absent

[dheydeck]

First, my compliments on this excellent project.
When listening to the following radio stations:
preset_00 = 79.120.77.11:8000/deltablues # 0 - Radio Caprice: Delta Blues
preset_01 = 79.111.119.111:8000/contclass # 1 - Radio Caprice: Contemporary Classics
The name of the station appears to be absent. If one of these is the first station to be listened to, just a hyphen followed by the track name is displayed:
"- Stockhausen - Gruss"
If a different station has been played previously, its name is prepended to the track name:
"Blue Skies Radio - Stockhausen - Gruss"

I have just recompiled with the 19-feb-2021 commit and the issue persists.

i could imagine it has to do with those colons but i'm not sure so maybe you just try it ?

Thanks, utw3v0- I really appreciate the thought. In fact the colons were originally hyphens, and I changed them to colons because I thought the hyphens might be the problem. The issue is the same in both cases! Here's an example of it working with colons:

I have submitted Pull Request #450, my first attempt so I may not have followed the correct process. The code nulls the icyname String prior to dbgprint ( "Switch to HEADER" ) ; and also caters for the case where icyname has not been populated and suppresses the hyphen that is usually present between icyname and the the stream title icystreamtitle.
Any suggestions/corrections relating to my use of GitHub are appreciated.
