Calling apply-imports in a template matching text() gets variable stack out-of-sync

           Summary: Calling apply-imports in a template matching text() gets
                    variable stack out-of-sync

I have one template which imports another one. In the first template, I have a
rule matching text(), which does some stuff and calls apply-imports. There is no
other text() rule in the imported stylesheets so the default rule is used. This
results in an extra "unlink()" call being made to the variable stack. In my
program, at the end of the stylesheet I get an ArrayIndexOutOfBoundsException
when the last "reset()" call is done on the variable stack.
I think the bug is in the method applyTemplateToNode() in TransformerImpl.java,
since there is an unlink in a finally clause. When apply-imports is called and
the rule is the default text fule, no link is done, but the finally clause is
executed anyway. I made an ugly patch for this and it made the bug go away.

Note: despite the name of this method, it seems to be called only for the root
node and any apply-imports rules.
