terminator crashes: TypeError: Item 0: Must be number, not str

[Benjamin Drung]

"terminator -e command" crashes when called via x-terminal-emulator symlink:

```
Traceback (most recent call last):
  File "/usr/bin/x-terminal-emulator", line 133, in <module>
    TERMINATOR.layout_done()
  File "/usr/lib/python3/dist-packages/terminatorlib/terminator.py", line 329, in layout_done
    terminal.spawn_child()
  File "/usr/lib/python3/dist-packages/terminatorlib/terminal.py", line 1482, in spawn_child
    self.vte.feed(_('Unable to find a shell'))
TypeError: Item 0: Must be number, not str
```

Steps to reproduce in a clean environment:

1. Launch ubuntu-22.04-desktop-amd64.iso
2. Try Ubuntu
3. Open terminal
4. Install terminator:
```
echo "deb http://archive.ubuntu.com/ubuntu/ jammy universe" | sudo tee -a /etc/apt/sources.list
sudo apt update
sudo apt -y install terminator
```
5. Run following command:
```
terminator -e "sh -c 'echo success; sleep 2'"
```
This command will open terminator and print "success".
6. Run the same command via the x-terminal-emulator symlink:
```
x-terminal-emulator -e "sh -c 'echo success; sleep 2'"
```

I've reproduced this. Bringing up preferences and making any change to trigger a ~/.config/terminator/config create makes the issue disappear. Maybe install should add the global /etc/xdg/terminator/config? Or rather than triggering this error, try to create a user config before declaring the error, only declaring the error if creating a default user config fails?
