Bug#25122: Views based on a self-joined table aren't insertable.

Browse source 
When INSERT is done over a view the table being inserted into is 
checked to be unique among all views tables. But if the view contains
self-joined table an error will be thrown even if all tables are used under
different aliases.

The unique_table() function now also checks tables' aliases when needed.
