patch 8.0.0282: need to use CTRL-O twice when in Visual-Insert mode

Problem:    When doing a Visual selection and using "I" to go to insert mode,
            CTRL-O needs to be used twice to go to Normal mode. (Coacher)
Solution:   Check for the return value of edit(). (Christian Brabandt,
            closes #1290)
