When default.storage.resource is empty, uploads fail

[JustinKyleJames]

Metalnx does not seem to use the server's default storage resource for uploads. Instead default.storage.resource must be populated.

If this settings is empty, uploads silently fail.

as we're moving to a pure client... it should not need to be set/defined on the client side.

i would expect it to defer to the server choice for default resource if it is not set in metalnx.properties.

I have the fix in. It requires changes to both metalnx and jargon-irods-ext.
