SVGHMI: Fixes UI lifecycle problems

Was sometime showing HMI tree of previously closed project : no more module globals to store hmi tree.
C++ dead object exceptions happened when re-opening SVGHMI UI or building after close of UI.
// widget_textstylelist.ysl2

widget_desc("TextStyleList") {
    longdesc
    ||
    TextStyleList widget is a svg:group, list items are labeled elements
    in that group.

    To use a TextStyleList, clone (svg:use) one of the items inside the widget 
    that expects a TextStyleList.

    In this list, only style matters. Text content is ignored.

widget_defs("TextStyleList") {
    |     styles: {
    foreach "$hmi_element/*[@inkscape:label]" {
        const "style", "func:refered_elements(.)[self::svg:text]/@style";
    |         «@inkscape:label»: "«$style»",
