ModuleNotFoundError: No module named 'google'

I'm having trouble installing pydgraph using pip, while this used to work before 2.0.0 (downgrading using pydgraph==1.2.0 does work).

Trying to install the protobuf or google packages before dgraph (as advised on StackOverflow) doesn't make a difference.

I think this is another instance of the issue fixed by this PR: #81

I'll release a new version of pydgraph with that change and verify it works.

@Tails I couldn't reproduce the issue on my machine (probably because I am not starting from an empty environment) but I released a new version of pydgraph with the fix. Can you verify it's working again for you? version number is 2.0.1

Fixed, thank you!
