Evgenii Stratonikov 0decb95591 [#625] morph/client: make all constructors return no error
In some places we panic, in some we return error, in some (audit) just return a client.
However in all of the places static client is created immediately before
the sugared-client creation.

This commit makes all constructors to just return a client for the sake
of code simplification and unification.
