Pull request diff end-point returns 302 with missing query parameters

For example:

https://bitbucket.org/!api/2.0/repositories/atlassian/stash-auto-unapprove-plugin/pullrequests/21/diff?context=0

redirects to:

https://bitbucket.org/!api/2.0/repositories/atlassian/stash-auto-unapprove-plugin/diff/gsylviedavies/stash-auto-unapprove-plugin:acfeaf6dc2e7%0D37b3eed9d931

But drops the context=0 parameter.

This will break existing integrations that rely on any context parameters passed to the pull request diff end-point.
