c-v will insert `:call paste#Paste()<CR>` instead of clipboard if use ale

win10
gvim8

I already found it's ale made this issue to my vim by commenting out other plugins.
if I comment out nothing but ale, the c-v work properly.

```
1.enable ale using vim-plug
2.copy something into clipboard
3(tested again, no need).select something in insert mode by shift + arrows
4.press
5.boom, `:call paste#Paste()` appear instead of clipboard
```

ale is a nice linter and uses every day so I hope this can be fixed quickly
thanks
