Sometimes we patch or edit a hook to meet our specific needs.
Somtimes this leaves behind a file like FILENAME.orig. The hook
detection login still runs these other files, making for confusing
debugging issues. Use a stricter match on what makes a valid hook name
to avoid these issues.

This reverts commit f1e05f8f.

Convert to our wrapper class for assertions

If the file system containing the PHP code is case-insensitive, a
request containing an uppercase file extension will return the
contents of the PHP file to the browser instead of executing it.

E.g. a request for this URL will return the source code:

  https:/sp.example.org/simplesaml/module.php/core/frontpage_welcome.PHP

Fix that by converting the path to lowercase before checking the file
extension.

See the following page for details:
