Reset normal mode before hiding the reload buffer info box

Reseting normal mode will enable normal mode, which will trigger
a check for buffer modification. We do not want that check to
happen as we are trying to close the info box. Doing that mode
reset first will prevent the check from happening (as the info
box is already displayed), and will correctly hide it afterwards.

Fixes #1809
