#473 solution task does not compile dependencies properly

When trying to compile a solution containing a project
that has hard references to specific assemblies while
reference paths to other newer references are present
the solution task will sometimes favor the newer version
and ignore or overwrite the older version. I have not been
able to determine the exact cause however for example
I have a project with a reference to 4.1.0.0 and inside
the project I have a reference path which is lower in the
list with the same assembly only version 4.3.0.0 the
task repeatedly copies in the 4.3.0.0 assembly instead
of the one specificly referenced. Both assemblies are
strong named.
