AvoidStandbyService suspend inhibitors left running after v1.3.2 test sessions

[ghubstan]

Description

There some Bisq shutdown scenarios that leave orphaned avoid standby service mode inhibitors.

Version

1.3.2

Steps to reproduce

1. Build v1.3.2 on a GNOME, Ubnutu 18 desktop

2. Start seednode, arbitrator, alice and bob instances in regtest mode after setting up dev / dao test env as per dao-setup.md

3. Perform wallet recovery tests as per ontestpad, for Alice and Bob instances

4. When all done, check for orphaned gnome session manager inhibitors:

    echo "All org.gnome.SessionManager Inhibitors..." 
    dbus-send --session --print-reply --dest=org.gnome.SessionManager /org/gnome/SessionManager org.gnome.SessionManager.GetInhibitors
   
     Result array is not empty:
   
      array [
             object path "/org/gnome/SessionManager/Inhibitor12"
             object path "/org/gnome/SessionManager/Inhibitor13"
             object path "/org/gnome/SessionManager/Inhibitor14"
             ...
        ]
   

Expected behaviour

Result array is empty; there are no orphaned sleep inhibitors:

      array [
        ]

Actual behaviour

Result array is not empty; there are orphaned sleep inhibitors:

      array [
             object path "/org/gnome/SessionManager/Inhibitor12"
             object path "/org/gnome/SessionManager/Inhibitor13"
             object path "/org/gnome/SessionManager/Inhibitor14"
             ...
        ]

Device or machine

Linux / Ubuntu 18

Additional info

Abrupt jvm shutdowns can result in ungraceful shutdowns, for example, when the OS sends a kill -15 signal to the jvm. Another scenario that may be causing this is when desktop shuts itself down after recovering a wallet from seed.

The bug is noticed by user when logging out of linux session, and he sees a "processes still running" warning (these are the orphaned inhibitors), but this does not block session logout, and inhibitors are shut down if the user clicks 'OK' (logout/shutdown).
