Proposed Changes

(Describe your changes here. Also describe the motivation for your changes: what problem do they solve, or how do they improve the application or codebase? If this pull request fixes an open issue, use a keyword to link this pull request to the issue.)

This PR fixes two issues with the assignment summary "Group" text filter:

1. It was erroneously including a boolean "inactive" member field in the search, leading to a runtime error
2. Its matching was case-sensitive rather than case-insensitive.

This PR fixes both of those issues.
