Log spam with the word "Plugged"

[eternal-sorrow]

Describe the bug
Logs get spammed with the word "Plugged" every 5 seconds (my configured interval for the battery module).

To reproduce
Reproduces with this config:

{    
    "layer": "top",    
    "position": "bottom", // Waybar at the bottom of your screen    
    "height": 27, // Waybar height    
    "fixed-center": false,    
    "modules-left": [],    
    "modules-center": [],    
    "modules-right": ["battery"],    
    "battery": {    
        "format": "{capacity}%",    
        "interval": 5    
    }    
}

Expected behaviour
No spam.

Screenshots
Not applicable.

Environment

• Waybar version: v0.15.0
• Installed from: gentoo portage
• Compositor and version: Sway 1.12

Debug output
Run waybar -l debug and paste any relevant output:

Tried it, nothing suspicious was found during the spam itself. Battery module says [debug] battery: worker interval is 5000 at startup, as expected.

I often see "Full" spam from the battery module too

I found the culprit:

Waybar/src/modules/battery.cpp

Line 689 in 90b209a

puts(status.c_str());

Yep, rebuilt with this patch:

The spam is gone.

Interestingly enough, this line is gone on master, but it is present in the 0.15.0 release, which causes the issue. Worth a bugfix release in my opinion.
