compctl completion required two tabs to load

[goarano]

This issue arises only when lazy-loading tools that rely on compctl for completion (e.g. pyenv).

It seems non-trivial to call the completion of compctl to obtain its results directly, therefore when _init_$func_name is called, the completion is cancelled. Only after a second is the correct completion function used.

If anyone has an idea how to fix this, let me know
