fix(mpris): defer widget visibility to update() to stop resume SIGSEGV

Browse Source 
The name-vanished playerctl callback called event_box_.set_visible(false)
directly. On resume from suspend this runs in a re-entrant / torn-down
state and crashes in Gtk::Widget::set_visible. Only clear the player and
dp.emit() from the callback; update() (on the main thread) computes
visibility from player state and hides the module when there is no player,
matching the other hardened handlers.

Fixes #5124.
