Prevent deprecation warning on LU

[KnutAM]

I get this deprecation warning from my tests:

┌ Warning: `LU{T, S}(factors::AbstractMatrix{T}, ipiv::AbstractVector{<:Integer}, info::BlasInt) where {T, S}` is deprecated, use `LU{T, S, typeof(ipiv)}(factors, ipiv, info)` instead.
│   caller = ip:0x0
└ @ Core :-1

(I don't understand why, but I don't see it when calling from the REPL)
As far as I can see, there is no need to provide any type-params to LU
(Sorry if I'm way off here, just wanted to avoid the warning during my tests. I suppose it isn't so crucial as the comment in LU says will be deprecated at Julia 2.0)

Run julia --help

Switches (a '*' marks the default value, if applicable; settings marked '($)' may trigger package precompilation):

 --depwarn={yes|no*|error}  Enable or disable syntax and method deprecation warnings (`error` turns warnings into errors)

no is the default, but tests run with yes.

Aha, thanks!
