patch 8.1.0696: when test_edit fails 'insertmode' may not be reset

Browse Source 
Problem:    When test_edit fails 'insertmode' may not be reset and the next
            test may get stuck. (James McCoy)
Solution:   Always reset 'insertmode' after executing a test.  Avoid that an
            InsertCharPre autocommand or a 'complete' function can change the
            state. (closes #3768)
