els_tooltip: Fix to use some functions before tooltip_test_set or tooltip_content_cb_set

Summary:
If user call tooltip_orient_set or tooltip_style_set or tooltip_window_mode_set
before tooltip_test_set or tooltip_content_cb_set, those functions doesn't work.
Because elm_tooltip will be created when tooltip_content_cb_set is called.
I fixed logic to use some functions before tooltip_test_set or tooltip_content_cb_set.

Test Plan: elementary_test -> Popups -> Tooltip
