[Building Sakai] Basic LTI tool registration settings being lost

You may need to upgrade the version of BasicLTI you're using in order to
get this to work. The version standard in 2.7.1 is pretty old, and Michigan
as well as clients on 2.8 were running version 1.3 which had a lot of bug
fixes around this area (configuration and properties) from what I remember.

There is a small patch needed to get 1.3 to compile under 2.7 because of an
API change in kernel (Which I think is actually in the
basiclti-2-6-x.patch<https://source.sakaiproject.org/svn/basiclti/trunk/basiclti-2-6-x.patch>)
but that should be it.
