Currently if an invalid FILE argument is passed to 'tvmc run' the user
will catch a traceback because exceptions are not treated, for instance:
$ tvmc run /tmp/nonexistingfile will throw a FileNotFoundError trace.
This commit catches the possible exceptions that can happen when an
invalid FILE argument is used and convert them to better messages for
the user so the invalid FILE can be easily spotted.
