More String.prototype.endsWith problems on Nashorn

[AprilArcus]

Now that 27b5630 and #1129 are merged, the original Nashorn error of Java::JavaLang::AssertionError (unknown call type GET:METHOD|PROPERTY|ELEMENT:call(Object)Object@jdk.nashorn.internal.scripts.Script$Recompilation$3$\^eval\_/0x0000000800765040) from #1128 has been addressed, and the polyfill can be loaded successfully. However, when I try to use a function such as endsWith, I get this new error:

Java::JavaxScript::ScriptException (TypeError: Can not invoke method [jdk.dynalink.beans.SimpleDynamicMethod boolean java.lang.String.endsWith(String)] with the passed arguments; they do not match any of its method signatures. in <eval> at line number 1)

The problem originates with the fact that Nashorn implementation of endsWith can't be called with the endPosition parameter:

> engine.eval("Function.prototype.call.apply(''.endsWith, ['foo',
 'o'])")
< true
engine.eval("Function.prototype.call.apply(''.endsWith, ['foo', 'o', 3])")
Java::JavaxScript::ScriptException

In order to correct this, the return value from uncurryThis should be falsey here:

Then the native implementation will be bypassed during this check:
