Subject: [PATCH] Fix tabbar drawing not updated when tab is erased

When a tab is deleted using `tabbar::erase`, `trigger::erase` is called. This function does not call `API::refresh_window` if the tab was erased successfully (unlike `trigger::tab_color`, `trigger::tab_image`, etc.), thus the tab is still visible until an interaction is made (like mouse click on `tabbar`).
