Fix version mismatch in @ngrx/store package.

[ItamarGronich]

• Versions 4.0.0 - 4.0.3 have a bug related to setting up metaReducers
  (Store: is metaReducers signature correct? ngrx/platform#264).
• We should include a package-lock.json top prevent those kinds of
  things
• package-lock.json will make sure we all have the same versions of
  everything.

@nirgn975 This is ready for review. I actually need this to continue my work on #351 so i'll merge this into that pr right now, and when it will later merge - America will be great agian.

[nirgn975]

There is not reason the keep metaReducers, we use Redux devTools chrome extension. So I remove them and upgrade ngrx to 4.0.7.

I'm closing this PR, re-roll from master in #351
