Need test for csvy models that have customized v_inner_boundary

[DeerWhale]

Is your feature request related to a problem? Please describe.
For csvy models that has v_inner_boundary value set to be in between the first and last shells, there were several places that the r_inner and/or v_inner still uses the value at the first shell instead of using the actual inner_boundary (the active shells), the modifications to fix this is in PR #2504

Describe the solution you'd like
However we still need tests that cover these changes. Especially for cases that have customized v_inner_boundary.
