Abspath instead of resolve

[alneberg]

Resolve would a source link to be uploaded with the name of what the link is pointing to and not the name of the link. I think the name of the link is what we should have.

A good test case is the following structure:

mkdir dir_with_contents
touch dir_with_contents/simple_file.txt
ln -s dir_with_contents dir_that_is_a_link
dds put -u unituser_1 -p project_1 -s dir_that_is_a_link
dds get -u unituser_1 -p project_1 -a

Prior to this PR the downloaded data would be inside files/dir_with_contents and after this PR it would be files/dir_that_is_a_link.
