fix rehydrating of feature module state

[nhaesler]

Currently rehydrating of feature module state doesn't work if you have keys defined in the root module. With every added module, the rehydration function gets called with the "@ngrx/store/update-reducers" action and syncs the initial state to the localStorage.

This change fixes it for me. On a quick glance it seems to fix the following issues: #75, #72, #64, #44

Do you think this is a fix that could have a unit test that fails without and passes with? I'm not a maintainer here but that would decrease the likelihood of this ever happening again.

I thought about it when submitting the PR, but it would probably be part of a unit test for the library as a whole, whereas now only parts of the library are tested individually. I'm not too familiar with the code and it was more of a quick fix because the whole library is more or less useless without it (if you use feature modules).
But it seems like @btroncone is busy otherwise at the moment so I don't know how alive the project actually is.

Can confirm this PR fixes rehydration of feature modules. Would love to get this merged + npm updated cos separately building @nhaesler's branch direct from GitHub is a PITA 😂

Is the lack of tests the only reason it hasn't been merged?

Sweet! When would the NPM package be able to be published with this fix?

Thanks

Very soon! Sorry have just been busy and it's my first time publishing so needed to read the docs. Will try to do today :)
