[0.13.12] Failure to restart sometimes after changing mods

[jonatkins]

Sometimes, when mods are changed, factorio exits and doesn't restart.

I've seen two cases:
1. just after the update to 0.13.12, I updated my mods. The update applied, but factorio just exited and didn't restart. Haven't tried reproducing this one as no mods currently have updates.

2. Toggling a mod between enabled/disabled.
a. launch factorio
b. enter the mod menu, toggle a mod, go back
c. factorio restarts (as expected)
d. enter the mod menu again, toggle the mod again, go back
e. factorio exits, but doesn't restart. Checking windows task manager shows no factorio process.
f. manually restarting factorio shows the mod changes applied correctly.

THe log files don't show anything helpful (specifically, the "Info AppManager.cpp:616: Restarting Factorio" message is there even when it fails to restart)

Running 64 bit on Windows 7, no command line parameters in use.

Should be fixed in 0.13.13.
