Fix date range gap.

[iM-GeeKy]

Motivation

• [x] Fixes https://github.com/web-ridge/react-native-paper-dates/issues/271 and https://github.com/web-ridge/react-native-paper-dates/issues/281. @RichardLindhout I'm not 100% sure if flex-basis is being used properly here, but it did achieve the desired effect. I'm not sure if this will cause any unplanned issues, but maybe you have an idea.

Before

After

Note - There are no guidelines on selecting a range to itself, but this is a potential existing style bug, that I noticed while playing around trying to fix this issue. @RichardLindhout Let me know your thoughts on this.
