Fix NamingTest on all Frog configurations

Fix NamingTest on all Frog configurations:
* throw the right exception even if the missing method was call$1
* fix a nasty escape bug in replaceAll ($ is a meta-char in the second argument of String.prototype.replace, so it must be escaped as "$$"). This bug is especially meta because the code that failed was str.replaceAll("$", "$$") ... but the bug could be triggered any time the "to" argument to "replaceAll" contained "$".

Well, actually this looks pretty awful to me - but that's the fault of the crazy
escaping rules we get to deal with and not your code.

File frog/lib/string_implementation.dart (right):

http://codereview.chromium.org/8763018/diff/1/frog/lib/string_implementation....
frog/lib/string_implementation.dart:51: to = to.replace(/\$/g, '$$$$'); //
Escape sequences are fun!
I wanted to suggest that you use @'$$' to simplify this - but the I realized you
were in JS <smile>.
