Launcher plugin: Multiple use-after-free Valgrind errors

Steps to reproduce:

1. Run "xfce4-panel -q"
2. Start "valgrind xfce4-panel"
3. Open a launcher properties dialog that currently contains 1 item (in the screenshot: Alacritty)
4. Add a second item (in the screenshot: About Xfce)
5. Close the properties dialog

See also: #442 (closed)

The above steps generate the following 30 memory access errors:
