Also add a test for when the first argument is null or undefined, as there are no tests that cover this currently.

The ES2015 specification requires that String.prototype.startsWith,
String.prototype.endsWith and String.prototype.includes use the IsRegExp
internal algorithm to determine whether to throw a TypeError to prevent
a RegExp from being accidentally cast to a String for those methods.
That internal algorithm checks the presence/truthiness of Symbol.match
to make its determination. This patch switches the builtins to use
this correct test, rather than checking for the [[RegExpMatcher]]
internal slot as the builtins previously did.
