Totara 13 stable version format

[sumaiyamannan]

Fixes the 'version number for Totara branches is 11 chars as oppose to the usual 10' issue.

Thanks Sumaiya - can you also drop that change in for the MOODLE_35_STABLE branch as well?

Ooh this is a clever little fix. We've never thought of using set_config we were using deployment scripts interfacing with cfg.php (which I'd guess uses that API under the hood anyways) if this ever happened :)

Wouldn't this break upgrades for plugins that are not exactly on the current latest version before this change?

At least based on commits here: https://github.com/catalyst/moodle-local_maillog/commits/TOTARA_13_STABLE/version.php

e.g. 20170111100 and 20190317100

Yeah good call - those versions are pretty ancient so I wouldn't expect to see them in the wild, but we could improve the check to prevent it from being a problem.. @sumaiyamannan can you please make that version check a little more flexible?

I have done it and created a PR #11
I had tested with version 20170111100 and 20190317100 and it worked smoothly.
