Deeplinks cannot be found in registry classes between 4.1 -> 5.1

I'm upgrading my company's DLD version from 4.1 -> 5.1. Based on your documentation all I needed to do was change any instance of the word `Loader` to `Registry`

I handle deeplinks by calling deepLinkDelegate.dispatchFrom(activity) and several of my integration tests (and actual implementation) have begun to fail. After doing some debugging I've found that entries in the registry that should match the provided uri are not matched by `idxMatch`

Start at deepLinkDelegate.dispatchFrom(activity) and inspect how idxMatch searches registry entries during the 4.1-to-5.1 migration. Reproduce the failing integration case and confirm the fix when a URI that should match is found and dispatched through the registry.
