Prevented FilesystemContext from resolving absolute paths

* there are situations where one may pass absolute paths to external functions which should not be resolved against the context path
** for example when reading files found by "read-directory" through its "full" value node
* this could be checked by the external functions themself
** but as this check is required by all of them it is better implemented in the FilesystemContext
