9aae4f2424 make tests compatible with Node.js 12 (#3304) 
In Node.js 12, the formatting of console arguments will change slightly.
Previously, a string other than the first argument was formatted using
single quotes if the first argument was non-string. Now, quotes are
never added regardless of position of a string argument.

To make test compatible in all Node.js versions, I work around by
ensuring the first argument to console.log is a string which prevents
the quotes from being added on older versions of Node.js.
