enfuseAdvanced won't load on Win10

[MeisterKaos]

As discussed in https://discuss.pixls.us/t/lua-updates-for-darktable-3-6/25686 enfuseAdvanced does not load on my Windows 10 machine currently. To reproduce:

1. Install darktable 3.6.0.1-win64 on Windows10.
2. run darktable (with empty user folder) via cmd: "\Program Files\darktable\bin\darktable.exe" -d lua > log.txt
3. Install lua scripts by clicking lua scripts installer > install scripts > execute
4. The script manager appears, click start/stop scripts > contrib > enfuseAdvanced stopped
5. See message "enfuseAdvanced failed to load" istead of "Loaded enfuseAdvanced "
6. See log.txt:
   4,671018 LUA ERROR : cannot open C:\Users\somme\AppData\Local\darktable\luarc: No such file or directory
   33,279368 LUA found win search match C:\Program Files\Git\cmd\git.exe
   85,188889 LUA ERROR: script_manager.lua: activate: 345: Error loading contrib/enfuseAdvanced
   85,188984 LUA ERROR: script_manager.lua: activate: 346: Error message: ...e\AppData\Local\darktable/lua/contrib/enfuseAdvanced.lua:873: attempt to index a nil value (field '?')

Any other script within "contrib" loads as expected.

Had you imported any images yet?

I managed to reproduce this by deleting my database files and my darktablerc so that when darktable started it looked like a fresh install. I didn't import any images, started enfuseAdvanced, and it crashed because when it sets up the widgets it checks the path of the first image in the collection, and if no images have been imported, then no collection, thus no path, thus crash.

So if you have any images imported and showing in the lighttable then enfusedAdvanced will work, but this does need to be fixed.

Yep, importing a few images solved the problem :)
Then I could also use the executable manager to set destinations of enfuse etc.. However, I still think that previously, after loading enfuseAdvanced I could set these paths in the options menu which I would prefer. But nevermind, now it is working. Thanks for your effort!
