Rethink "Seen on [date]" in list of seen movies

[wtimme]

Is your feature request related to a problem? Please describe.
When I start using the app, I want to put movies that I have already seen on the (empty) "History" list. After adding a movie, the list says "Seen on [current date]". This is not correct - I have only marked it as seen at that date.

(I've seen this movie a couple of years back - not just some minutes ago.)

Describe the solution you'd like
For the MVP, I propose we rephrase this to "Added on [current date]".

Describe alternatives you've considered
I might not be getting the purpose of this "History" screen.

Additional context
Personally, I initially thought of this as a list of movies that I watched and can recommend. Especially since the "call to action" in the empty state is worded like this:

You don't have any movies you have already seen on this list.
Go ahead and add a new movie.

As a new user, this sounds like I could have a collection of movie recommendations.

I really like the idea of just changing the wording. There is another issue open #90 where you could change the date on which you watched the movie. But until this feature is implemented, I love the wording suggestion! Do you want to make a PR for the wording change?
