Config overwrite bugfix (#363)

* Fix bug where on parsing an alternate new config it will overwrite main config.json in gct dir

* Stop movement of config.json file from root dir when a new config is parsed in

* Stop overiding config.json at gct dir with new config.json from root directory

* RM LN :D

* Fix bug where promptforconfig in config_encryption.go overwrites default config
Ensure periphery command packages do not interact or save over configuration
Ensure tests to not save over or change current testdata/config
