parser: Do not push token back before parseheredoc
When we read the first token in list() we use peektoken instead of readtoken as the following code needs to use the same token again. However, this is wrong when we're in a here-document as it will clobber the saved token without resetting the tokpushback flag. This patch fixes it by doing the tokpushback after parseheredoc and setting lasttoken again if parseheredoc was called.
