+Changed the way project slug is extracted from an entity. Up until now, the plugin assumed that the project slug is always of the format "owner/repo". However, this is not something that is enforced by Jenkins and sometimes the project name doesn't contain an owner.
+Since this split is not used anywhere and the entire project slug is always used as-is, removed this distinction and just read the project slug from the annotation as-is.
