RFR: 1306: IssueNotifier fails to update Resolved In Build for issues with *-oracle fixVersion

[Erik Joelsson]

In SKARA-1146 I made the IssueNotifier for build tags only update Resolved In Build in issues where the fixVersion of the issue/backport matches the version in the build tag. I missed taking fixversions of the format N-foo into account. This patch addresses this by comparing just the number components of the JdkVersions so ignoring the the "opt" part.

I chose to just adjust an existing test case to cover this case instead of creating a new one.
