Target property not imported if we extend the reported reactor

[erlingrj]

If the imported reactor is instantiated it works as expected, but if it is extended it does not.

Example:

In ImportMe.lf

target C {
  cmake-include: "Include.cmake"
}
reactor R {
  reaction(startup) {= =}
}

target C 
import R from "./ImportMe.lf"
reactor R2 extends R { }
main reactor {
  r = new R2()
}
