fix: new episode notifications for subscriptions not opening series page when clicking

[Bnyro]

There are multiple scenarios where the previous approach fails at the moment:

1. When the extension uses JSON data to as dataUrl, handleIntentData tries to match the JSON data to the main url of the engine, which obviously won't work because the JSON data isn't prefixed with the mainUrl
2. If the mainUrl is different to the used dataUrl for the series (e.g. because the mainUrl is the HTML url for the extension, but the internally used urls refer to the api url for the extension), there's no match
3. There are various multi-providers that accumulate stream sources from different sites but use TMDB internally to reference series (i.e. their TMDB URL). However, such providers either don't provide any mainUrl, and if they do, it's not guaranteed that the user will land on the right extension when clicking the link, because multiple providers possible use the same mainUrl.

The idea in this PR is to use the api name in order to identify the origin of the notifications dataUrl, so that the right api can be found (by its name).

Nice catch!
