Checking settings file existence before attempting to read them

[Gijom]

Thanks for this great plugin. However after installation I was constantly having troubles with errors of the type ENOENT "Could not find file /path/to/local/config/litexrc and /path/to/latexfile/.litexrc". Of course creating those files would resolve the problem but why bothering when the plugin works out of the box ?

Solution:
I just added a line for testing the existence of these files before opening them in the function load-settings and used the files/file? LT function for that purpose.

Out of curiousity, are you using LT 0.8? This isn't a problem in 0.7,
so I'm wondering if this was introduced in the switch to Electron.

Yes I do have LT 0.8.1. Note that the plugin was working despite of the error messages (6 error messages in total, 3 per local/wide settings). The proposed modification solved the problem (at least for me).

Glad to hear it's (mostly) working. I still haven't gotten around to
the upgrade, and I wasn't sure if anything would be broken. I'll merge
in the change shortly.

Thanks!
