Deprecation warnings in setup.jl

[homocomputeris]

Obviously, not a breaking issue at the moment, but may be worth fixing:

┌ Warning: `haskey(o::PyObject, s::Union{Symbol, AbstractString})` is deprecated, use `hasproperty(o, s)` instead.
│   caller = numargs(::PyObject) at setup.jl:9
└ @ Main /usr/lib/python3.7/site-packages/diffeqpy/setup.jl:9
┌ Warning: `getindex(o::PyObject, s::Symbol)` is deprecated in favor of dot overloading (`getproperty`) so elements should now be accessed as e.g. `o.s` instead of `o[:s]`.
│   caller = numargs(::PyObject) at setup.jl:13
└ @ Main /usr/lib/python3.7/site-packages/diffeqpy/setup.jl:13

#46 should do it but it seems to fail? Is this PyCall master or something?

[homocomputeris]

I believe I have the release versions:

(v1.1) pkg> status
    Status `~/.julia/environments/v1.1/Project.toml`
  [764a87c0] BoundaryValueDiffEq v2.2.3
  [2b5f629d] DiffEqBase v5.8.1
  [aae7a2af] DiffEqFlux v0.5.0
  [0c46a032] DifferentialEquations v6.4.0
  [61744808] DynamicalSystems v1.3.0

Can you look at that PR? I believe I followed the depwarns correctly.

That failure may be due to #42.

If I update setup.jl, I get this:

and also this:

julia> hasproperty
ERROR: UndefVarError: hasproperty not defined
julia> using Base
julia> hasproperty
ERROR: UndefVarError: hasproperty not defined

And I failed to find docs for JuliaLang/julia#30496 in 1.1 because it requires 1.2.

@stevengj should https://github.com/JuliaPy/PyCall.jl/blob/fffd933828a559b794d1aadbe4273e76e5d8f84e/src/PyCall.jl#L341-L344 only throw a depwarn on v1.2?

[tkf]

I think you can use PyCall.hasproperty here.
