Specify height instead of minHeight in account selector

RelativeLayout inside ListView (in ListPopupWindow) easily
confuses itself with layout_height="wrap_content" and hard to
figure out why it is shown wrongly.

Though the exact problem just happens with phone but tablet,
it would be better to use the same way in tablet UI for safety.
