The application display name is not very nice

Should probably be something like "XWiki Authenticator and Contacts".

Solution:
1. because the length of the name should be less than 30 characters in the console of google play, So I update the name as "XWiki Authenticator & Contacts" in the google play store.
2. the name in android maybe don't need to modify because it doesn't show in home launcher and it's just in the system settings -> accout. no need to change.
