Produce a single library for multiple file dependencies on the same file
Previously, the Gradle plugin’s ProjectLibraries produced a new library for every file dependency, even if the dependencies where on the same file. This would lead to a repackaging failure due to multiple libraries having the same name. This commit updates ProjectLibraries to treat file dependencies on the same file as a single library, thereby resolving the name clash. Fixes gh-1646
