Fix running SNP pipeline against PR manually

[DomAyre]

When running the SNP pipeline manually for a PR, the PR id field isn't populated so the pipeline treats it like a run on a non-pr branch, meaning it gets the latest SHA from the merge branch rather than from the merge commit message as expected.

Fix is to look for the merge branch instead
