Fix the attempt of graceful alignment for Hovercards

Browse source 
Summary:
Refs T1048; Fixes T2902 - (Probably) fixes @vrana's issue. I managed
to repro it on Ubuntu FF (though on Windows with 1.0GHz/512MB it's
really worse...).

This revises the approach to the graceful degradation for
`too-far-to-the-screen-edge-edge-case`.

I noticed that `x` could become very negative, up to about ~`-170px`.
This is due to the //"already-on-the-left-side"// nature of object tags.
`50 - 200 - 20` = `negative`. Adding `100px` (node.dimension.x / 4) to
that won't really help, as the hovercard would still be offscreen.

Instead, display them left-aligned with the object tags on the left edge
per default, and offer centerization in center cases. This is also better
for Pholio, Phriction, which have a way lower min-x than Maniphest,
Differential.

I also disabled placing the hovercard below the tag in case there's not
enough space on the north side. The hovercard would not display 99.99% of
the times after being hidden (and it retains the flickering behaviour).
Another reason is also our current hide-behaviour, which only assumes
north-side alignment. Adding south-side didn't really work (I'm bad with
JS), so I didn't bother with it. Disabling this is //acceptable//, since
it only really affects Pholio, Phriction. And nobody places object tags
in the first line, anyway. Except for my test pages, of course :/

Btw, this also removes the weird jaggy horizontal shifts for object of
various lengths (e.g. `{D4356}`, `{rP32ofhw0842obw}` etc.). I think
that's only good.

Test Plan:
Hovered in Pholio, Phriction in Chrome, FF. Did not touch
left screen border.

Hovered in Maniphest, Differential. Tags farther to the left were
aligned left, tags more in the center were pretty centered.
