fix for copy pasting valid phone number

[anees17861]

There is an issue of copying a valid phone number with country code. The code appends the selected country code resulting in invalid number. To solve this I've copied the content of set(phoneNumber) to didEditText().
It solves another issue where the selected country code doesn't match the code in pasted number

The code can be improved if set(phoneNumber) returns a boolean to wether it was a success. This helps improve client code as well since invalid numbers can then be handled better. Example use case is picking from contact picker with wrong number
