Ctrl+I doesn't work in editor when hovers are deactivated

Description

What steps will reproduce the problem?

Pressing Ctrl+I on any object on the editor should display help in the Help windows if you have it enabled in Preferences.

1. Under Help in Preferences, turn on Ctrl+I for both the console and editor.

2. In the editor, type ‘print’ on a blank line, put the cursor in front of the p, and press Ctrl+I. Nothing appears in the help window.

3. In the IPython console type ‘print’, put the cursor in front of the p, and press Ctrl+I. Documentation for print correctly appears in the help window.

This can only happen if hovers are deactivated in our Preferences. We need to think how to decuple help from hovers.

We could send the hover request regardless if it is activated for doing hovering. Right now, the LSP protocol does not offer any alternative mechanism to retrieve signatures, besides the textDocument/hover request

Good call, I agree with that.
