`$or` and `$and` operators do not work

[shirouto]

Hi there.

It appears the mongo operators are not properly instrumented when they appear inside arrays/lists. For example something like:

{and: [{field1: {eq: val1}},  {field2: {eq: val2}}]}

will not be properly resolved. Specifically, eq will not be transformed to $eq.

The issue seems to be because the code in the template mongoke/templates/resolvers_support.py that does not recurse through lists (only dictionaries). Something like shirouto/mongoke@f88a539 seems to fix it.

Cheers
