[Console] Fix autoselecting last request (elastic#218001)

Fixes elastic#194257

## Summary


This PR fixes the bug in Console where, if there is a request on the
last line of the editor, it gets automatically selected when the editor
is open. This is because the cursor is initially placed at the last
position of the edition, and if this position turn out to be at the end
of the request, the request is selected because the editor is on focus.
We fix this by not focusing the editor initially (i.e. there is no
blinking cursor when you open the editor) - this ensures that there
won't be any initial request highlighting as per the logic on the
following line:
