Prevent panic when checking for db config secrets. This could happen when the connection resource does not have any optiosn block defined and we are trying to update it.

Does this actually happen in practice? I assumed there were always some connection options defined, regardless of connection type.

I was able to reproduce this with something like:

resource "auth0_connection" "this" {
  name                 = "gh854"
  is_domain_connection = false
  strategy             = "auth0"
  realms               = ["gh854"]
}

As when we expand the options we read them just from the config, not from the state as we use the raw config.
