Fix empty project UI

In an empty project, the 'project is empty' light well was mashed up against the project panel. The light well have 16px margin so there was some white space along the edges that looked funny. This MR makes the 'project is empty' text block a `gray-content-area` which fits nicely with the rest of the UI.

Don't display "git clone --bare <URL>" if no URL is available

Make it clear that forking is different than importing. Forked repositories don't use `import_url`, so only display if is available. Introduced in !1231

Import forked repositories asynchronously to prevent large repositories from timing out

Preserve synchronous mode of adding a repository since some tasks (e.g. restore/check) require the former.

One side bug fix is that the `ProjectCacheWorker` is also run, updating the repository size and commit numbers properly. Previously all the values were set to 0 when a project were forked.

Fix tooltip display in list views

After the recent UI changes the tooltips in a list view rendered behind the next object. This resets the tooltip's container to the body, rather than the individual `issue-info` div. In particular, this change will be applied to *all* tooltips in GitLab. This should take care of any other unidentified issues like this and should not have any negative effects that I can think of. This fixes the bug I noted in !1255.
