Show tests only for specific project if it was selected from project list

[pashidlos]

As it's now tests for all projects are shown regardless /test?project_id url param

Steps:

1. navigate to /project
2. select any project

Actual result:
tests for all projects are shown

Expected result:
show tests only for specific project

@MitkoTschimev what do you think on this one?
was is as a part of functionality or it's something new?
should we also hide project filter in case project_id provided?

[MitkoTschimev]

yes -> I think we should definitely support this.

So the filter service should be able to manage the query params and the query params should support all filter options and not only project.
