Default string-length() to the context node

string-length() with no argument failed to compile with "must have at
least one parameter". XPath 1.0 section 4.2 makes the argument
optional and defaults it to the string-value of the context node, so
`//title[string-length() > 10]` should work.

Use the same self::node() default as normalize-space(), and reject more
than one argument instead. The invalid-expression test now checks the
two-argument case.
