templater: fix ifcontains() to evaluate items argument eagerly

See the previous patch for why. An "items" argument may be a string,
a generator, or an arbitrary container object.

    if not (3 <= len(args) <= 4):
        # i18n: "ifcontains" is a keyword
        raise error.ParseError(_("ifcontains expects three or four arguments"))

    item = stringify(args[0][0](context, mapping, args[0][1]))
    items = args[1][0](context, mapping, args[1][1])

    if item in items:
        yield args[2][0](context, mapping, args[2][1])
    elif len(args) == 4:
        yield args[3][0](context, mapping, args[3][1])
