Not placed at the right place. From your log file:

open source     > level 2, order 3, name '/Users/jan-erikhagglof/context/context-osx-64/tex/texmf-local/m-circuitikz.mkxl'

(I am surprised it gets found! The should be texmf-local/tex/context/ sub-dir)

open source     > level 3, order 4, name '/Users/jan-erikhagglof/context/context-osx-64/tex/texmf-context/tex/context/modules/mkxl/m-tikz.mkxl'

(I am guessing that this is the old m-tikz.mkxl).

For such experiments, it is simplest if you place the files in the current directory.
