Fix the password box not removed after entering protected mode

Implementing doRefresh(.) for ProtectedSessionTypeWidget fixes the issue mentioned in #1078.

Maybe a default implementation for doRefresh(.) in TypeWidget would be better?

Kindly check my comment here:
#1078 (comment)

your fix, would be correct, from what I can tell – as it implements the "doRefresh" method, which got turned into an abstract method in the commit e16f4a1

not sure what the reason was, but there will have been one I guess

@eliandoran what do you think?

also: the previous "default implementation" was indeed exactly what you did in your commit here, so it should be OK I think.

Previous "default implementation" in type_widget.js:

async doRefresh(note) {}
