fix: disable 'copy to clipboard' checkbox when 'copy file location' is also selected

spectacle previously allowed copying both the image as well as file location simultaneously to the clipboard. This MR also attempts to fix a corner case which requires 'Autosave image' to be enabled to 'copy file location to clipboard'. Previously, if 'Autosave Image' checkbox was not enabled, it was still possible for the user to copy the file location to clipboard. However, this had indirectly triggered an autosave first. This is confusing, as spectacle saves the file to its default save location without it being asked to. So it would be ideal to disable 'Copy file location' if 'Auto Save' option was not enabled in the first place
