Don't warn about mismatched versions when using multiple patches for the same library

I just found out about https://github.com/ds300/patch-package/issues/43 which will make our patches really easy to work with by separating patches from each other. What a great feature!

Unfortunately we have enabled --error-on-warn to ensure we keep our patches up to date, and so the warnings we get from multi-patch names causes our builds to break.

I've patched patch-package with patch-package locally to skip + version patches, to work around this and avoid the warning. I'm sure there are some gotchas with the .includes('+') syntax I've used here (NPM versions that include the + character?) but I thought I should submit this as an issue to see whether it could be applied.

Here is the diff that solved my problem:
