Move user#show and group#show routing under root url

## What does this MR do?

Changes routing so user#show and group#show routing is under root url 

## Are there points in the code the reviewer needs to double check?

no

## Why was this MR needed?

For nice and consistent routing  for user/group show pages:

| before | after| 
|---|---|
| `/u/dzaporozhets` | `/dzaporozhets`| 
| `/dzaporozhets/gitlab-ce` |`/dzaporozhets/gitlab-ce`| 
| `/u/dzaporozhets/snippets` |`/u/dzaporozhets/snippets`| 
| `/groups/gitlab-org`|  `/gitlab-org`| 
| `/gitlab-org/gitlab-ce`|  `/gitlab-org/gitlab-ce`| 
| `/groups/gitlab-org/issues `|  `/groups/gitlab-org/issues `| 

So show page for user and group shown as `/:name` which is much nicer than before. At same time all nested pages like group issues stays under REST `/groups/:name/issues` so we don't need to introduce extra name restrictions ( ex. case when group has project with name "issues")

Closes #21169

See merge request !6314

The Sortable concern has a default scope that adds ORDER BY to all
queries. EXPLAIN ANALYZE shows that this additional ORDER BY statement
causes the SQL optimizer to use the wrong index, which leads to a load
time of 2.9 s vs 0.073 ms just for the SELECT call. The minimal
change here is to re-implement find_by using where and reorder to
remove the ORDER BY clause in IssuesController#index.

Closes #23075

Only hide deploy status external link on x-small screens.

## What does this MR do?

Fixes [a regression](https://gitlab.com/gitlab-org/gitlab-ce/commit/03ea01946524a74773b24430c81804c2724b84b6#68dead621eaa630b5150a4d71b59fa3cd19030fd_57_50) where the deploy status widget hides only the text within the widget, and only for screens within bootstrap's 'small' range (≥544px - <768px).
 
## Are there points in the code the reviewer needs to double check?

I changed the viewport width range to hide the widget from `sm` to `xs` because when the external link is removed, it seems to fit comfortably even on xs viewports. 

Given that we were already hiding the external link (along with all of the deploy text) on `sm` viewports, I assume it's okay to hide the external link still, instead of wrapping it to a new line. 

We could remove the conditional hiding altogether though, and allow the external link to wrap. Definitely doesn't look as nice, but if it's important to show the external link along with the deploy status, we could make it look better when it wraps.

## Why was this MR needed?

Looked buggy, and prevented context being given for build passed icon on smaller screens.
