Playlist cycling via presets is broken in 0.14.3

[alackmann]

What happened?

In my 0.13.x installation of WLED, you can create a preset with the API command similar to P1=20&P2=22&PL=~ that when triggered will cycle through playlists 20,21,22 and then back to 20. These can be triggered either from the WebUI by pressing the preset OR from an external button macro (among others).

In all the 0.14.x versions I've tried, this is no longer working. Instead it repeatedly triggers the first playlist in the list. So in the example above, the playlist in preset 20.

To Reproduce Bug

• Create 3 new playlists via the UI. In this example using IDs 20, 21 & 22 for the presets. Put different presets within each playlist.
• Create a preset (can be any ID, but let's call it 3 in this example) that has the API command P1=20&P2=22&PL=~ as the preset content
• Using the web interface, click on the new preset 3
• Playlist 20 will play
• Click playlist 3 again
• Playlist 20 will restart again

Expected Behavior

• On the second click, playlist 21 should play.
• On the third click, playlist 22 should play
• On the fourth, the cycle should restart and playlist 20 should play

Please try JSON API instead of HTTP API.
I.e. {"ps":"20~22~"}

Neither were working @blazoncek. My PR fixes both.

It breaks other (legacy) things.
