Dependent rules with paths that must not exist may evaluate on outdated rmObject

[EBrader]

Create PathsThatMustNotExistFixer with similar purpose as for AssertionFixer that removes pathsThatMustNotExist from the root asserted during rule evaluation so that next evaluated rules take non-existence into account.

Fix applies only for paths that must not exist referring to object instance of Pathable with parent being any instance of ItemStructure, Cluster, Composition or Section. This limited set is the result of needing to know the actual type of the parent in order to call relevant methods to either delete the child from a list or set a value to null. If the desire is there to support all types, almost for all existing RMObject types, a check and cast would be needed.

To be able to import the objects from project openehr-rm, testImplementation needed to be changed to api in build.gradle of tools.
