v1.6.2

This fixes a potentially critical bug, where a component would enter an infinite rerender loop,
when another hook triggers an update. This may happen when multiple useQuery hooks are used in
a single component or when another state hook triggers a synchronous update.

• Add generic type-parameter to client.query and client.mutation, by @ctrlplusb (see #456)
• ⚠️ Fix useQuery entering an infinite loop during SSR when an update is triggered (see #459)
