Return all results of project autocompletion

Since we now limit the search results, we don't have to filter
subprojects of a matched project.
Before this change a search for 'hom' would return no result. Although
there are many projects of the form 'home:$login'.
Now it would return the first 50 projects that start with 'hom'.
