Title: bslalg_hashtableanchor.t: Fix -Wunused warning.

Fixes the following:

```
../groups/bsl/bslalg/bslalg_hashtableanchor.t.cpp: In member function ‘bool PtrHashSet::insert(void*)’:
../groups/bsl/bslalg/bslalg_hashtableanchor.t.cpp:501: warning: unused variable ‘found’ [-Wunused-variable]
```

The `found` variables is only referenced in `BSLS_ASSERT_SAFE`, so put the block in a `BSLS_ASSERT_SAFE_IS_ACTIVE` check.
