Reset banner bug fix

[lauslim12]

Hello!

This PR fixes the bug as explained in issue #17, the changes are simple:

• The cause of this bug is in the reset() function in the src/components/app.jsx file. Previously, it was made to reset the currentDetails value to beginners-wish in the React state variable (I believe this is the cause of the problem). I fixed the problem by removing the currentDetails and adding the selectedWish state variable whose value is the current banner that the user is browsing on when he/she clicked the reset button.
• Next, I adjusted the else statement in the src/components/banners.jsx to not set the selectedBanner state variable to beginners-wish. That way, when we clicked the reset button, we will still remain in our currently selected banner, not scrolling back to the Beginner's Wish.
• I haven't updated the version number yet, just in case.

I have tested it in my web server (this includes last PR (#16) changes), and it works like a charm! No more switching to the beginner's wish if we rolled after clicking the reset button!

Don't forget to re-run npm run build after merging my previous and this PR, because I made this PR based on your master branch, not my cache-busting-improvements branch 😅.

I think that's all. Hope it helps and thank you!

Resolves #17
