Invoking chatgpt-shell opens two buffers on first call instead of one

[alej0varas]

Steps to reproduce

1. Set (setq chatgpt-shell-always-create-new t) in your configuration.
2. In a new Emacs instance ensuring no chatgpt-shell buffers exist.
3. Run M-x chatgpt-shell for the first time.

Expected behavior

Only one chatgpt-shell buffer should be created on the first invocation.

Actual behavior

Two buffers are created after the first invocation. Subsequent invocations correctly create one additional buffer each time.

Additional info

• Setting chatgpt-shell-always-create-new nil results in only one buffer as expected.

df7b6ee should fix it. Please give v2.26.2 a try (beware you'll need to update shell-maker also for an unrelated change)
