    e-categories: Show migration runtime warning only if the file exists
    
    The categories migration code can fail on the first install on the machine
    where was no old or new Evolution installed, but the runtime warning was
    printed even in case the source file was not found, which is in most
    of the cases and, more importantly, it's not a real problem when the file
    is missing.
