When setting the entry description in LTI 1.3 Deep Link it does not make it into Lessons

Install an LTI 1.1 and LTI 1.3 Tsugi store.   Add Learning App using 1.1 and 1.3.  When adding the learning app - change the title and description before sending the tool back to Lessons for installation.  The tool-provided title and description appear in the right places in the LTI 1.1 placed tool - but when the tool is placed using 1.3, the title is correct but the description is a copy of a title rather than the description suggested by the tool.

This turns out to be an error in Tsugi - Sakai is working correctly.  But I am going to make a patch to Sakai to (a) check for empty values of the title and description more reliably and (b) remove the "TODO" comment in Sakai where I wondered why this was not coming back form Tsugi.  I think the confusion had to do with Tsugi working with a draft spec at one point.

This is fixed in Tsugi as of https://github.com/tsugiproject/tsugi-php/commit/0bd9131dd69b72ab56e718dc7228be3cca518d8f
