Steps to reproduce:

1. start plugin
2. configure Global pipeline libraries to use cache
3. create a pipeline to use Shared library
4. start the pipeline and aborted during scm retrieve process
5. build logs displays an error
6. start the same pipeline again

Expected: shared library retrieved from scm and pipeline success

Actual: pipeline fails with error: `Library global-pipeline-library expected to contain at least one of src or vars directories`

because `global-libraries-cache` contain cache but it's empty.
