Use RemoveAll instead of Remove
Use RemoveAll instead of Remove

Several places use os.Remove and check for os.ErrNotExist.  os.Remove
does not return os.ErrNotExit, it returns a *PathError so these remove
calls will panic if the file does not exist.

Instead use os.RemoveAll that will not return an error if the file does
not exist.

Fixes #4545
