Fix google-translate functionality

This bug exists already since I started using Spacemacs about 1.5 year ago.
Because it was already reported upstreaim in
[this issue](atykhonov/google-translate#52), I
implemented this fix only locally.

However it becomes time now to implement this fix globally, to fix the
google-translate functionality by default.
