Add src string to copyDirectory error message.

WRidder · WRidder · commit 38f946779f57 · 2019-08-19T22:14:04.000+02:00
Proposal to display the wrongful `src` path in the error message. For example, this error can popup in the Microk8s Kubernetes deployment dashboard. A notion of which src path is referred to would be helpful.
