Fix crash in runtime if PSK secret is missing

/* This project contains wamp client config to be loaded at runtime startup. */

./project_files/wampconf.json

wampconf.json is in "Project Files", so it is copied to runtime's working directory, and then loaded after program transfer + runtime restart.

Otherwise, wamp config file path can be forced :

./Beremiz_service.py -c /path/to/my/wampconf.json /working/dir
