fix(StatusBaseButton): keep `MouseArea` enabled when in `loading` state

`StatusBaseButton` comes with a `MouseArea` that is disabled when the
button is set to being disabled. Prior to this commit it's *also* disabled
when the button is in `loading` state.

This makes sense because a button that is in `loading` state shouldn't
not emit any click signals or trigger hover indications.

There's a scenario though in which we want render a tooltip on top of
the button which is in `loading` state. For the tooltip to show, the
`MouseArea` of the button needs to be enabled.

Hence, this commit adjust `StatusBaseButton`'s behaviour to *not*
disable the `MouseArea` when it's `loading`. Mouse events are already
prevented via the `loading` flag. So the only thing left to do is to
ensure the button doesn't trigger any hover indication when in `loading`
state.
