Load web3-fx to for :web3/call and other fx-s (#15)

* Load web3-fx to for :web3/call and other fx-s

If these effects are not loaded, re-frame doesn't know how to handle
them. They could be added in the application that uses this library
(district-ui-web3-tx), but this is more convenient.

* Use updated version of district0x.re-frame/web3-fx

The 1.0.7 version bump fixes compilation error with newer Clojure versions.
