(PC-17083) fix(Home): fix modules not loading on homepage

[yorickeando]

Link to JIRA ticket: https://passculture.atlassian.net/browse/PC-17083

Module loading is triggered by the call of onEndReached on the react native Flatlist. It is a current bug of React Native that onEndReached is sometimes only called once because of race conditions between two flatlist behaviors. We do notice that onEndReached is indeed called once when this bug occurs.

This pull request transfers the logic inside onEndReached to onScroll, more reliable.

Our hypothesis is partly based on these discussions.

The bug was not only on disconnected users, but it was made more visible because of the lack of displayable modules in the batch of modules made available by the first and only onEndReached. For geolocated users, about 10 module ere shown so the fact that no more could be loaded was less noticeable.
