Disabling "active" filter also disables "hover" filter

[Imbecillus]

Description

Setting the filter for the state "active" to 'none' also disables any filter set for "hover".

Steps to Reproduce

1. Create a chart (e.g. a pie chart) with a filter for "hover" but no filter for "active" (see the reproduction link)
2. Move the mouse over the pie sections.

Expected Behavior

The chart's sections are highlighted on mouseover as described in the filter. There are no visual changes when a section is clicked.

Actual Behavior

There are no visual changes for either mouseover or clicking. This also applies to bar charts and probably other chart types as well.

Further notes

This seems to have been introduced with the fix for issue #180. In Graphics.js, the hover filter is only applied when a filter for the state "active" is set and not operating on a touch device:

pathMouseEnter(path, e) {
    // ...
    if (
        w.config.states.active.filter.type !== 'none' &&
        !w.globals.isTouchDevice
    ) {
        let hoverFilter = w.config.states.hover.filter
        filters.applyFilter(path, i, hoverFilter.type, hoverFilter.value)
    }
}

Resulting from this, the hover filter is never applied if there isn't also a filter for the "active" state.

As far as I can tell, if the code only checked whether it was operating on a touch device and the condition w.config.states.active.filter.type !== 'none' was removed, the bug from issue #180 would still be solved.
