project: move --reference handling to project-objects

Browse Source 
When using --reference, the path is written to objects/info/alternates.
The path is accessed inconsistently -- sometimes through projects/ (via
self.gitdir) and sometimes through project-objects/ (via self.objdir).
This works because projects/.../objects is a symlink to the objects dir
under project-objects/.  Change all accesses to go through self.objdir.
This will allow us to stop symlinking projects/.../objects without the
reference dir logic breaking.  The projects/ path is going to use its
alternates file for its own needs.
