CRM_Core_I18n - Fix usage of `getPath('[foo]/.')`

The interpretation of `/.` is evolving per #16735:

* When this code was first written, it was unspecified/variable whether the value `[foo]/.` would end in `/`
* During most of the testing of 5.23.beta1, this was defined to always return `/`
* During a regression fix in 5.23.1, we're flipping it back the other way so that `[foo]/.` never ends in `/`.
