[FIX] project: fix tags filtering based project for mobile view

Before this commit, when we click on the tag field in mobile view
it will display all the tags because in mobile view it will open
the kanban view on click of m2m field so 'search_read' called
instead of '_name_search'.

So in this commit, fixes the issue by applying the same filter
domain in search_read.
