Rename of static accessor method fails to rename property-style access w/o object expression

Consider the following:

package a
class B {
  static def getX() {}
}

import static a.B.getX
x

x is a static method call expression for getX. Renaming getX in B properly renames the static import reference, but fails to rename the static method call expression.

Note: This happens because the static import is renamed in the first phase of the rename refactoring. Then the rename participant is called to find property-style accesses. At that time, type inferencing cannot establish the connection between the expression x and the static import, which now refers to the new name for the accessor.

See #678 for more details

Reproduce the rename refactoring with the Groovy classes and static import shown in the issue, then trace the static import rename and the later property-style access lookup. Use #678 for related context. Done means renaming getX also updates the property-style x call without breaking the static import reference.
