Fix unwanted redirect from search index to edit on login error

The search action saves searches including:

  @template=index|search

The code strips:

  @template=index

but not the error condition template.

So when an non-logged in user uses a search with
@template=index|search and fails to log in, their displayed page is
the search edit page (template search) not the search display (template
index).

This change strips both forms when saving. I don't know if this needs
to be generalized to strip additional templates. But it solves te
orignal issue with search displays jumping to edit mode on login
failure.
