Resolved multiple unexistent file error

* Resolved a big issue in switch command if prime_logfile not exists, file check added
* Added non existent file handling in various parts of script (next-boot, log-view, unset, current_check)
Those issues manifested themselves after a fresh installation, because some config files still were not present
