Update LTI xblock

[pdpinch]

the LTI Xblock has been updated a few times since dogwood, including some changes that Kyle made to support SGA-LTI. Although I don't know of any use case for SGA-LTI on the residential stack, it seems prudent to make the update now -- especially since MatLab may be depending on this XBlock.

I believe 1.0.9 is the most recent version. See https://github.com/edx/edx-platform/pull/12683/commits/8ce63fef9b8c9d53902add65421784879858231c

Cherrypicked in mitodl/edx-platform#1

I've been testing this with sga-lti, which has a dependency on version 1.0.8 or greater. It isn't working in my test course:

https://dogwood-qa-draft.mitx.mit.edu/courses/MITx/TEST101/2014_Spring/courseware/aec449f629c247f4b1e656318b46c48f/1d54a85e837d4ce7ad1b7995af0f7cce/

I suspect that the update to xblock-lti-consumer didn't take properly, because it doesn't seem to be passing the fields that were added in version 1.0.8, namely:

lis_person_contact_email_primary:"pdpinch@mit.edu"
lis_person_sourcedid:"pdpinch"
custom_component_display_name:"Assignment+1"

In addition, I also noticed that we're passing the wrong server name:

resource_link_id:"lms-staging.mitx.mit.edu-i4x-MITx-TEST101-lti_consumer-70c9fbb233be436594bb28572d0ef113"
lis_outcome_service_url:"https://lms-staging.mitx.mit.edu/courses/MITx/TEST101/2014_Spring/xblock/i4x:;_;_MITx;_TEST101;_lti_consumer;_70c9fbb233be436594bb28572d0ef113/handler_noauth/outcome_service_handler"

Different error today:

@blarghmatey would you mind confirming (again) what version of xblock-lti-consumer we have on dogwood-qa-draft.mitx.mit.edu ?

This has been successfully upgraded with the latest deployment.

XBlock dependencies are deliberately vague in xblock-lti-consumer (https://github.com/edx/xblock-lti-consumer/commit/32a320acbd1a2d54360c99b207e4ebd6751ec15a) but the changes that we need should have been complete with 1.0.7. Let's try that.

This has been updated and installed. It should be ready for testing.
