Rtest3 (#2448)

Improve li_std_vector_vector runtime test for R

- Fix unittest_sequence to fail if elements don't match.
- li_std_vector_vector testcase fixes.

Replace list with c because vectors in R are not exactly lists,
therefore comparing vectors (returned by C++) with R lists
complicates things a lot. Added as.integer because by default
numbers are numeric and I guess we want to check the exact type
returned by C++ which is integer the first check fails because
make_vector_int returns a vector of strings (containing numbers),
not integers (in the previous version this test would pass
because R does an implicit
