fix: Reset cursor blink when moving selection (#1903)

### Problem description
When this feature was implemented the text editor handled all the
keyboard input so the blink reset function could be called in one place
for all the key presses. Now that shortcuts are done in the shortcut
manager we need to reset the blink state inside all the functions that
can affect cursor movement.

### Implementation description
Every function that moves the cursor now calls the blink state reset
function at the very start. There may be more functions that need this
that haven't been merged but git should show merging conflicts so it
should be easy to deal with.
