Daniel Llorens 96f7332263 array-contents returns root for empty arrays with empty root 
This fixes a compiler issue where (uniform-array->bytevector #2f64())
failed because of the stricter definition of uniform-vector? on this branch.

Perhaps it would be better if uniform-array->bytevector didn't require
a contiguous argument.

* libguile/arrays.c: (scm_array_contents): return the root regardless of
  the value of SCM_I_ARRAY_DIMS (ra)->inc.
* test-suite/tests/arrays.test: check.
