Automatically adjust width in overflow menu & Android

We don't want that:

Solution

Thus, we should ignore the user setting of the width there and just set width: auto, which lets emoji-mart use all width it has.
Maybe the same for height?

TODO

• As we may also need this in OfflineQr, for Introduce smart QR code size handling and remove user options?  offline-qr-code#187, make a common lib to determinate where a page is running.
• implement this issue here based on that lib

(I temporarily fixed it by choosing ‘11’ columns in the preferences, but it should be automatic)
