SaveLastSessionLayout blocks exiting

[ethsol]

Thanks for the SaveLastSessionLayout plugin by @vssdeo.

Unfortunately it interferes with closing the terminal, it hangs.

Steps to reproduce:

1. Back up your terminator config file:
   cp -p ~/.config/terminator/config{,_$(date -I).bak}
2. Create a config file which only contains this plugin:
   echo -e "[global_config]\n enabled_plugins = SaveLastSessionLayout" > ~/.config/terminator/config
3. Test it to see hanging:
   start terminator
   press Shift+Ctrl-O to open a new pane.
   Now comes the bad part: press Ctrl-D to close the terminal.
   It does not close just hangs.
   Press Alt-Up to move to the upper pane.
   Press Ctrl-D to try closing this pane as well.
   It doesn't close just hangs.
   Close terminator
4. Now let's check whether terminator works without the SaveLastSessionLayout plugin.
   Create a config file containing only a \n:
   echo > ~/.config/terminator/config
5. See terminator working well:
   start terminator
   press Shift+Ctrl-O to open a new pane.
   press Ctrl-D to close the terminal.
   Pane closes, only one terminal remains open.
   Press Ctrl-D to close this as well.
   It works.
6. Restore your normal terminator config file:
   cp -b ~/.config/terminator/config{_$(date -I).bak,}

So the culprit should be the SaveLastSessionLayout plugin. Can you please repair it?

Thanks @ethsol for finding the issue and giving a detailed report. Can you help me with a few details since I am not able to reproduce.

1. run terminator with -d and attach the logs here
2. can you enable any other plugin and see if the same bug appears
3. if possible can you try the same on your same machine using the github master code.

meanwhile I will try again to reproduce, may be I am missing out a step or two
