Displaying Tests page is too slow

[Masayuki Igawa]

At Tests page[1], there are too numerous data by default. So it consumes a lot of memory and time to display itself. And it's hard to find anything in there now. A kind of workaround is proposed[2]. But we should resolve this by introducing tiers, adding more efficient filtering, pagination, something else.

(It may also need to change subunit2sql for introducing the pagination.)

    Split tests page into list and detail page

    This commit splits the tests page into a list page and its detail page
    for improving the performance of showing the page.
    Previously, we rendered numerous tests list in one tests page. So it
    causes the performance issue. Splitting the page reduces the number of
    showing test lists. This is not perfect solution but it's better than
    before at least.
