xfce4-applications.menu should be reloaded on next write after a parsing error

Link to original bug (#14167)

Description

Currently, if malformed write is made to xfce4-applications.menu, xfce4-panel will stop trying to read the file (after showing a parsing error). xfce4-panel should continue listening for writes made to xfce4-applications.menu.

This might be a garcon bug, feel free to move it in that case.
