GitHub import: Run housekeeping after initial import

See merge request gitlab-org/gitlab-ce!26600

After an initial fetch, the repository will have many loose objects
and refs. Running a `git gc` will compact refs into `packed-refs` and
objects into `.pack` files, which should make importing pull
requests faster.

Handle possible HTTP exception for Sentry client

Closes #60149

See merge request gitlab-org/gitlab-ce!27080

Prior this commit exceptions raised during a HTTP request
weren't caught by the Sentry client and were passed to the user.

In addition the Sentry client tried to catch a non-existent error
`Sentry::Client::SentryError`.

Now, the Sentry client catches all possible errors coming from
a HTTP request.
