Compensate for missing trailing semicolon
Compensate for missing trailing semicolon

The govuk_frontend_toolkit stuff uses different javascript
formatting than us where they begin their files with
semicolons but don't end files with them.

Our JS does the opposite, and so concatenating the files
results in a compilation bug somewhere in the middle.
