Unable to query metadata that ends in .xml or a /

[andrewbcoyle]

This appears to be similar to #193. We are upgrading from 1.1.0 to 2.1.x. Currently I am testing 2.1.2. I am finding that, although all our SP metadata fiels are in our metadata aggregate used for MDQ, when entities ending in .xml or a trailing slash do not return metadata. They just return "Not found".

I apologize if this is a duplicate request, but I do not see any proposed solutions. How can we get pyff to query all entityID's no matter their spelling?

Pipeline with specifics removed:

- when update:
    - load:
        - /$my_aggregate.xml
    - break
- when request:
    - select
    - pipe:
        - when accept application/samlmetadata+xml application/xml:
             - xslt:
                 stylesheet: tidy.xsl
             - first
             - sign:
                 key: /$my_key.key
                 cert: /$my_cert.crt
             - emit application/xml
             - break
        - when accept application/json:
             - discojson
             - emit application/json:
             - break

E.G. for entityID "http://alation.com/" In the logs I see 2025-06-02 16:24:47 INFO pyff.builtins selecting using args: ['http://alation.com'] indicating the trailing slash is removed.
