Use Drupal.t() correctly

Working on it.

Hi @narendrar,
I've parsed through whole codebase and corrected Drupal.t() where required, please check.

I have verified that all the Drupal.t() usages are now correctly used and changes look good to me, so marking this RTBC.

Mostly looks right to me, but I think you missed a spot :)

Hi @phenaproxima,
I've made the changes pls look.

Looks good to me!

Hard to manually test visually-hidden things, but we got there!
