Summary: Fix a bug in xquery.value.ValueSequence.getHashKey()

Initial Comment:
This patch fixes a stupid bug in xquery.value.ValueSequence.getHashKey()

for example, if we have the following two elements to group by $item/a/text() and by $item/b/text(), 

<item>
  <a>12</a>
  <b>1</b>
</item>
<item>
  <a>1</a>
  <b>21</b>
</item>

These two element came in the same group because the hashKey for each element was "121". 

Now it's "12&&1&&" and  "1&&21&&" (sentinel character "&" is added between atomic  values of grouping keys).
