Fix logical replication slot initialization

This was broken in commit 9c7d06d60680, which inadvertently gave the
wrong value to fast_forward in one StartupDecodingContext call.  Fix by
flipping the value.  Add a test for the obvious error, namely trying to
initialize a replication slot with an nonexistent output plugin.

While at it, move the CreateDecodingContext call earlier, so that any
errors are reported before sending the CopyBoth message.
