Customize resolve-path handle to handle absolute paths

The :resolve-path operation will always resolve the path based on the relative-to attribute.
In the messaging subsystem, we have a different behaviour where the relative-to attribute is ignored (whether it is defined or not) when the path value correponds to an absolute path.

To be consistent with this behaviour, the :resolve-path operation builder would need customization and specify that the relative-to attribute must be ignored when the path is absolute.
