fix(@angular/cli): correctly handle --search option in ng doc

When the `--search` option is passed to `ng doc`, it should open a URL
that does a search across the whole website (instead of the default
behavior of limiting the search to API docs).
Fix the `ng doc` command to implement the iteded behavior (previously,
it did the opposite).

(cherry picked from commit 9f5550e)
