Entropy exclusions ignored when using scan-remote-repo

🐛 Bug Report

When running tartufo with scan-remote-repo the entropy exclusions in the remote repo's tartufo.toml are not being used.

To Reproduce

1. Take any repo with entropy exclusions defined in a tartufo.toml that is committed to the remote repo.
2. Clone it and scan it locally with the scan-local-repo option
3. Now scan it using the scan-remote-repo option making sure that you aren't in a directory with a local tartufo.toml
4. You should see differences in the output, specifically that high entropy patterns that should be excluded are now showing as issues from tartufo when scanning the remote repo.

Expected Behavior

When running tartufo with the scan-remote-repo option on a remote repo that contains a tartufo.toml, all exclusions defined in the tartufo.toml in the remote repo should be respected and used.

Code Example

mgaspar-godaddy/tartufo-scan-test provides an example repo where this behavior can be seen

Environment

Python 3.9.11
Tartufo 3.1.2
