single-instance@2.5.4

f83c5d3b (#3584 by @vincentkoc) On Linux, a secondary instance that cannot deliver its arguments to the primary instance now returns a plugin initialization error instead of exiting successfully, and an invalid dbus_id returns an error instead of panicking. When the session bus is unavailable the app keeps launching normally, without single-instance support, and logs a warning.
b53d1984 (#3686 by @lucasfernog) On Windows, an argument containing a | is no longer split into several arguments when it is forwarded to the running instance.
