jscript: Return ParseProcedureText when compile fails.

Browse source 
This prevents crashes when there is an invalid script
inside a tag property.

Because ParseProcedureText calls release_bytecode without
checking if compile_script failed, "code" is not set, and
this leads to a crash when release_bytecode tries to access it.
