[messaging-app] added contact is half hidden in compose view

[Olga Kemmet]

Steps to reproduce:

1. Open Messaging app
2. Carry out a bottom edge swipe to compose a new message
3. Type a letter into the input box in the header, to add a contact
4. Select a contact from the proposed list view

Actual result:
The selected contact moves to the left in the input box and is half hidden, even though there is enough space to show it completely. There seems to be a lot of space between the name and the blue cursor.

Expected result:
The just added name/contact should be visible in full if it fits into the input box, including the cursor. The space between the end of the contact and cursor should be reduced.
The same happens if you type in a number manually and tap into the message input field, the number moves out of the view, even though there is enough space to show its full length.
A contact number can only move out of view, if it doesn't fit fully into the input box in the header.
