Gross patch for tailscale.py

[brandonscript]

There is some weird behavior (#1262) where the client expects a dict and the API is now (?) returning a list, as well as mismatched property casing (snake hair_pinning vs. camel hairPinning).

This is not the "correct" way to fix it, but it will at least get things working again.

Proposed Changes

Not actually proposing these changes, but demonstrating the problem and a workaround for anyone who needs this temporarily patched.
