Deeplink: fix web url with custom app scheme transformed to link

[pyby]

Motivation and Context

First try in production #85 worked from https urls shared in mails, message or whatsapp.
But it does not work on a shared url in Facebook application, which open Play web in the internal Facebook web browser.

Play web uses in html header <meta data-react-helmet="true" property="al:ios:url"palysrf://www.srf.ch/play[…]>.
The JS parsePlayUrl parses correctly the urls but as the micro page url is transformed to a link?url=, it keeps the app custom scheme.
It creates a loop and the application stays on the home page.

Description

• Update JS parseUrl with a correct https link redirect even if app custom scheme url was given if the deeplink conversion is link?url=.
• See https://github.com/SRGSSR/playsrg-mmf/commit/860b1b2bcf9f43cd9ae4512dc53cb8ac6dfdf463 fix and tests.

Tested with Play SRF debug build on an iOS simulator and middlewareURL configuration url using the deployment of the PR:

xcrun simctl openurl booted "playsrf-debug://www.srf.ch/play/tv/micropages/_test-serien-mit-charakter?pageId=11faeeab-eb48-4192-93cf-22e99f1543b8"
