Update return values of install and install_symlink

These now return an Array of all the target destinations.
Previously, if a single argument was passed a single non-
Array was returned.

This behavior has been changed so that an Array is always returned
even for a single argument.

Updated the test.

Hopefully this won't break any custom code out there.
