fix wrong timestamp

[hamano]

ISO 8601 define basic format:
YYYYMMDDTHHmmss
and extended format:
YYYY-MM-DDTHH:mm:ss

but jlib:timestamp_to_iso() makes:
YYYYMMDDTHH:mm:ss

https://en.wikipedia.org/wiki/ISO_8601#Combined_date_and_time_representations

Either basic or extended formats may be used, but both date and time must use the same format.

If you hate the change, It's a good idea that we make new functions timestamp_to_iso_basic() and timestamp_to_iso_extended().
Thank you.

We have 1 and 2 argument version of this function and both do something different (2 argument version formats time stamp as defined in http://www.xmpp.org/extensions/xep-0082.html while version converts to older time stamp format as defined in http://xmpp.org/extensions/xep-0091.html). Switching name of 1 argument version to for example timestamp_to_legacy_timestamp would probably be not that bad idea, but we still need both of those versions.

Additionally i think we can't remove those '-' and ':' from 2 argument version, per xep-0082 only variation that have those is correct.

So i can't accept this pull request, but if you would want to do that 1 argument version rename, i would gladly accept it.

OK, I didn't see thir XEP.
I'll rename timestamp_to_iso/1 to timestamp_to_legacy/1 and
add new function timestamp_to_iso_basic/1.
Thank you!
