`cider-eval`: support re-rendering the Inspector buffer when `cider-inspector-auto-select-buffer` is set to nil and there's a `*cider-inspect*` buffer shown in a non-visible frame

[vemv]

My overall intent is the possibility to have the *cider-inspect* buffer permanently on a background frame. cider-eval would have that frame's cider-inspect buffer re-rendered, without switching to it, given that I personally find that only a fraction of evals deserve inspection.

This wasn't possible before, as CIDER would detect that my frame wasn't visible, so it would render the buffer in a random window of the visible frame.

Commits:

• cider-popup-buffer-display: Do nothing if the intended buffer is visible in another frame and select is nil
  • This seems the right thing to do, for a wide variety of use cases.
• cider-eval: support re-rendering the Inspector buffer when cider-inspector-auto-select-buffer is set to nil and there's a *cider-inspect* buffer shown in a non-visible frame
  • This supports the workflow of using the inspector occasionally (less intrusively), but ready to be shown anytime.
• cider-overlays: Make Result truncated message more accurate
  • If there's already a *cider-inspect* buffer visible, we shouldn't suggest the user to inspect the value again.
