Title: support for specifying id attributes (used on SAML 1.1) and fixed unit tests

In SAML 1.1 the assertion looks like this

```xml

....

YJKsLS3YhUrUUFR3VlHUggBkaAmYmzTl0OWPyQDnN5g=Fr24......rd

```

Notice the ID pointing to AssertionID. So I added an options to the ctor of signed xml to be able to pass a custom id attribute. Also refactored a bit so that it fallbacks to 'Id' and then 'ID'.

Fixed some unit tests that were failing (not because of this)
