Rename refactor on static member should not impact aliased references

[eric-milles]

Consider the following:

import static C.m as x
class C {
  static m() {}
  static {
    this.m()
    this.&m
    C.m()
    m()
    x()
  }
}
@groovy.transform.CompileStatic
class CS {
  static m() {}
  static {
    this.m() // not C#m
    this.&m // not C#m
    C.m()
    m() // not C#m
    x()
  }
}

Rename Refactoring (Alt+Shift+R) on C#m should update "m" references but not "x" references. Currently the "x"s get changed as well. Same goes for static fields and properties.
