terraform: Fix fetching modules

Starting with commit 36437f18 (PgBouncer deployment with terraform,
2020-07-29), we've introduced a new dependency on the pgbouncer module
for Terraform. To download the module, the commit in question added a
call to `terraform get`, which causes us to download the module. But as
we're only executing `terraform init` in case no `.terraform` directory
exists and `terraform get` will unconditionally create that directory,
the result is that `terraform init` will never be executed.

Fix the issue by just removing the call to `terraform get`.
Initialization will fetch the pgbouncer module anyway, so there's no
need to do it explicitly.
