templates: fix error report with multiple messages

Fix the definition of javascript code to generate a correct
message window for multiple error messages.
The error is cause by a redefinition of 'let bgclass' in multiple
lines when the html template receives multiple error messages.
Each iteration to generate the code for the error messages tries
to redefine the variable bgclass and it causes the js to fail.
