Make saving the configuration more robust (#594)

* feat: Make saving the configuration more robust

* parse backup user config before return

* fix some bug

* Add write-userconfig.js and invalid-config.bin

* throw exception if failed user config parsing

* Merge branch 'master' into feat-467-make-save-more-robust

* hide keymaps and macros if agent in restore mode

* fix Device name settings
