Fix direct_upload for old records

See merge request gitlab-org/gitlab-ce!18360

Old records have a null value of file_store column.
This causes the problems with current direct_upload implementation,
as this makes it to choose Store::REMOTE instead of Store::LOCAL.

This change moves the store save when change saving the object.

[Rails5] Avoid type casting in uniqueness validator

See merge request gitlab-org/gitlab-ce!18470

Before this change, trying to setup dev environment could be tried
without having at least one Gitaly running. Cloning the repositories
would fail, but not stop the setup.

Given this would lead to an inconsistent state, a check was added if we
could connect to the server.

Output when it fails:

```
$ rake dev:setup
Failed to connect to Gitaly...
Error: 14:Connect Failed
```

Previously we scheduled a worker to just some this but we were running
into performance issues when the build table was getting too large. So
now we've updated the code such that this column is updated immediately
and incremented/decremented by the correct amount whenever artifacts are
created or deleted.

We've also added the performance optimization that we do not update this
statistic if a project is deleted because it could result in many
updates for a project with many builds.
