Broken parsing URIs with single slash after scheme

[serhiy-storchaka]

As @shagren reported, parsing URIs with single slash after scheme does nor work. imahe:/{user}/{name} is resolved to image://{current_cluster}/{current_user}/{user}/{name} instead of image://{current_cluster}/{user}/{name}.

For example:

$ neuro images
image:/mvasilkovsky/neuromation-mask-detector

$ neuro image tags image:/mvasilkovsky/neuromation-mask-detector
ERROR: {"errors": [{"code": "NAME_UNKNOWN", "message": "The repository with name 'neuro/shagren/mvasilkovsky/neuromation-mask-detector' does not exist in the registry with id '771188043543'"}]}
