Calling residual! instead of jacobian!

[oriolcg]

Hi @JordiManyer, I was doing some code profiling (an issue to be reported/addressed in Gridap) and I found this possible error:

GridapSolvers.jl/src/BlockSolvers/BlockFEOperators.jl

Line 64 in 26aa6f9

residual!(A,op,u)

I think here it should be calling jacobian! instead of residual!, right?

Hi @oriolcg , The BlockFEOperators are halfway-implemented. I need to re-define the API and add functionalities that I want to have. I am currently tied into other things, I'll probably leave this for version 0.4.
