When DFS cluster mount point path does not exist, an exception is thrown at times (for example when running composer install / clearing caches).

However, the exception message displays an empty string instead of the actual (configured) path.

Steps to reproduce:

• Configure cluster with unexistant mount point path ("nfstest")
• Clear caches

Result: the message is incorrect.

$ php ezpublish/console cache:clear
Clearing the cache for the dev environment with debug true
