The CI job `test-services-linux-debug` executes the tests using CMake,
including the Go tests. The command used to execute the Go tests is
defined in `CMakeModules/testing_go.cmake` Ln14: `go test ${test_source_files}`.
The `go test` command first compiles the tests and then run them.
Compiling the tests needs the file
`common/go/src/asapo_common/version/version_lib.go` to correctly define
 the versions of the different communication protocols and components:

```go
package version

// Default build-time variable for library-import.
// This file is overridden on build with build-time informations.
func init(){
	version   = "100.0.wip-fix-tests, build 5100fbee"
	consumerProtocolVersion = "v0.6"
	producerProtocolVersion = "v0.6"
	discoveryApiVersion = "v0.1"
	authorizerApiVersion = "v0.2"
	ftsApiVersion = "v0.2"
	brokerApiVersion = "v0.6"
}
```

The file `common/go/src/asapo_common/version/version_lib.go` is
generated when running CMake. So the file is generated in the CI job
`build-services-linux-debug`, not in `test-services-linux-debug`.

This commit ensures that the file is copied from the CI job
`build-services-linux-debug` to the CI job `test-services-linux-debug`
so that `go test` can use it when compiling and running the tests. If
the file does not exist, `go test` won't be able to compile the tests.
