Typing r.table_list() into Python repl throws an error

[coffeemug]

Type this in the repl:

import rethinkdb as r
r.table_list()

Output:

Traceback (most recent call last):

Note, I'm not trying to send it to the server. It's likely a printing bug.

Yeah. Looks like this will throw anytime we try to print a 0 argument AST node.

Note that this is another issue that would have been caught by proper backtrace tests.

This is in review 638 by @coffeemug

The underlying issue is the duality between r.table_list and r.db(...).table_list(). We try to print both as the latter but choke when we find there is no db argument. The same applies for table_create and table_drop.

This is in v1.6.x and next.
