hover-after-completions

I've tried into why the hover-after-completions test fails in the recent travis builds (e.g, #235, #233). If I understand correctly, eglot-completion-at-point calls eglot-eldoc-function in its exit-function with the intention of displaying the eldoc documentation. However, depending on the the eldoc-timer, soon eldoc will check whether there's a documentation for the current point. Since completion-at-point (C-M-i) is not in the eldoc-message-commands, eldoc will clear the echo area, and set eldoc-last-message to nil.

So instead of calling eglot-eldoc-function at the end of elgot-completion-at-point. Eglot cloud (eldoc-add-command 'completion-at-point) in eglot--managed-mode.

However, following João's philosophy, I think eglot should not implement this feature. If users want to see documentation after completions, then they should add (eldoc-add-command 'completion-at-point) to their init files, or try to ask the eldoc maintainers to modify eldoc-edit-message-commands to return completion-at-point as well. In the mean time, it might be a good idea to draw attention to the eldoc-add-command in the readme.

@nemeth hover-after-completions is passing again. Are you sure this is still needed? Let me know and I will re-open.
