Use != instead of is not for values.

This uses the `==`/`!=` operators instead of `is`/`is not` when checking
the return value of RPC calls. In Python, `is not` tests if the two
operands are the same object whereas `!=` test that they have the same
value. `is not` just happens to work for small inters due to an
implementation detail in CPython (e.g. see [StackOverflow]).
