Subject: MqTabLabel: Only restore normal title if custom title set

Otherwise, mq_tab_page_set_title() tries to unblock a WebKitWebView

Fixes:

    (marquee:...): GLib-GObject-WARNING **: /build/glib2.0-B1uXKV/glib2.0-2.50.3/./gobject/gsignal.c:2602: handler '128' of instance '0x...' is not blocked
