Fix check_remote: Check for REVISION file with archive update_code_st…

…rategy and check for .git folder with clone update_code_strategy

With update_code_strategy === ‘archive’ there is no .git folder and therefore the check is never executed.

After updating from v6 to v7, an error occurs because the REVISION file does not yet exist.

My suggestion would be to use the REVISION file for update_code_strategy === ‘archive’ and the .git folder for update_code_strategy === ‘clone’.
