* parser.y: Bugfix, I think. :) We do not need to call the expander

for a Lisp expression in a quasistring, and doing so leads to a
potentially incorrect double expansion because the whole thing
will be expanded again, either by the TXR Lisp quasi operator's
expander (if this is a quasiliteral in Lisp) or in the TXR
pattern language, by expand_meta, which hunts down down @ expressions
and expands them.
