Error when pulling change from remote that adds two or more non-IRIS code files

[isc-pbarton]

Steps to replicate:

1. Set up two local git repos cloning the same remote
2. Set up an IRIS instance using git-source-control configured with one of the repos
3. On the other repo, add two files that are not IRIS code. Commit and push to the remote.
4. With VS Code server-side editing the IRIS instance, open the Server Side Source Control menu and click the "Pull changes from remote branch" option.

I get a frightening message in the output window:
