Reason: we removed support for mutually inductive datatypes from the

fix(library/tactic/cases_tactic): try to clear input hypothesis when performing dependent elimination
...
The `induction h` tactic tries to clear hypothesis `h` after it is
applied. But, before this commit, `cases h` would only try to clear `h`
when performing non-dependent elimination. This was problematic when
writing tactic scripts for automating proofs.
