CopyStep does not expand macros

1) FilePathAspect::expandedValue() does not use the Macro Expander.
2) CopyStepBase::CopyStepBase() does not set the Macro Expander on the Aspects

Steps To Reproduce:
1) Open some project
2) Add a deploy step "Copy File"
3) Set some marco as input / output
4) Try to run (set breakpoint in CopyStepBase::init())
