ash: parser: Do not push token back before parseheredoc

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.
