Fix dialpad floating button in all contacts tab

When call initiated from all contacts tab in dialer
while call in progress press home button, open
dialer application again and press back, floating
button showed with the dialpad drawable in all
contacts tab instead of add contact drawable.

Fixed by adding check for showing dialpad drawable
on floating button only for speed dial and history tabs
