Title: Fix empty contact filter not working properly

If you want to start a new conversation with the "+" button, the "Select Contacts" window is shown. When you enter part of the name the filter is working as expected. But if you delete the filter again, just the TextSecure users are shown, not the rest of the contacts.

The filter needs to be checked for an empty string aswell, not just for null.
