[FIX] pos_restaurant: runbot random error on clicking table

Checking the log of the runbot error, there is an extra `create_from_ui`
rpc call for `restaurant.floor`. This is because when table T4 is clicked,
it is still an `EditableTable`. It is possible that the full rendering after
toggling edit mode isn't complete and the tour proceeds because it sees
table T4 in the dom, when in fact the table we want to click should not be
`EditableTable` instead a `TableWidget`. This is random because the tour
may proceed as long at it sees the trigger element, even if the owl
rendering is not finished.

In this commit, we make sure that we click the correct element which is an
unselected table. So we check if table T4 is unselected before clicking
table T4 to open the product screen.

To reproduce, follow instructions here: https://gist.github.com/caburj/ef311076a24d898132ed9c6b99367581
