chore(library/constructions/brec_on): suffix _1 is not needed when naming brec_on functional param

Reason: we removed support for mutually inductive datatypes from the
kernel.
This change is relevant for the new goal tagging feature.

The changes were applied manually to make sure all changes are
compatible with our plans to `induction`.

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.
