Description:
    lxqt-panel(taskbar): Sensors Widget forgets custom colors when re-opening the Configure Panel
        window (booted in live mode).

Expected results:
    Custom colors on the Sensors Widget should stay set until I say so.

Actual results:
    Custom colors on the Sensors Widget are coming and going as they please when I re-open
    the Configure Panel after setting custom colors on the Sensors Widget.

Steps to reproduce:
    0.Boot live cd or usb.

    1.Right-click taskbar, select "Manage Widgets", the Configure Panel window will open.

    2.In the Widgets section of the Configure Panel window, click plus sign(+) on the right hand
      side, this will open the Add Plugins window.

    3.Scroll down in the Add Plugins window and select: "Sensors(sensors)"
                                                        "View readings from hardware sensors.",
      then click Add Widget button, you should see the Sensors widget appear on the right hand end
      of the taskbar, then click Close button.

    4.Back in the Configure Panel window, select the Sensors widget you just added, then click on
      the gear icon on the right hand side, opening the Sensors Settings window, and select the
      sensors tab.
      In the column named Color, click a blue (default color) rectangle to open the color picker
      and select a bright color for contrast, click OK, you should see the Sensors widget on the
      taskbar display the new color.

    5.OK, here's where it gets good, close all the taskbar config windows you have opened,
      then right-click taskbar, while looking at the Sensors widget, and select Manage Widgets,
      for me, the colors get RESET to default blue.

    6.Now, if you navigate all the way back into the color picker(step 4.) and just click OK,
      with or without selecting a new color, it seems to re-parse and reapply the custom color(s)
      (until you right-click taskbar again, and select Manage Widgets)

Tested variations:
    0.What happens when I logout>login?. Picked colors seem to be honored.

Comments:
    I know this is not a particularly egregious bug, but this is my first bug report
    and I need practice.

    I tend to run Lubuntu in live mode for my daily driver, and for testing .iso qa.
    I use the ram/cpu/temp widgets to monitor heavily loaded machines compiling,
    SETI@home, block mining, etc.

Affected versions.
