test: wrap assert.fail when passed to callback

Currently there are many instances where assert.fail is directly passed
to a callback for error handling. Unfortunately this will swallow the
error as it is the third argument of assert.fail that sets the message
not the first.

This commit adds a new function to test/common.js that simply wraps
assert.fail and calls it with the provided message.

Tip of the hat to @trott for pointing me in the direction of this.
