json: Fix latent parser aborts at end of input
json-parser.c carefully reports end of input like this:
token = parser_context_pop_token(ctxt);
if (token == NULL) {
parse_error(ctxt, NULL, "premature EOI");
goto out;
}
Except parser_context_pop_token() can't return null, it fails its
assertion instead. Same for parser_context_peek_token(). Broken in
commit 65c0f1e9558, and faithfully preserved in commit 95385fe9ace.
Only a latent bug, because the streamer throws away any input that
could trigger it.
Drop the assertions, so we can fix the streamer in the next commit.
