The current validation only checked for the
number of elements in the volume-spec, however,
did not validate if the elements were empty.
Because of this, an empty volume-spec (""),
or volume spec only containing separators ("::")
would not be invalidated.
This adds a simple check for empty elements in
the volume-spec, and returns an error if
the spec is invalid.
A unit-test is also added to verify the behavior.

the `convertVolumeToMount()` function did not take
anonymous volumes into account when converting
volume specifications to bind-mounts.
this resulted in the conversion to try to
look up an empty "source" volume, which
lead to an error;
undefined volume:
this patch distinguishes "anonymous"
volumes from bind-mounts and named-volumes,
and skips further processing if no source
is defined (i.e. the volume is "anonymous").
