[4.3] guided tours - assets table

[brianteeman]

Steps to reproduce the issue

1. open and save any installed tour
2. create a new tour

check the assets table

Expected result

com_guidedtours has a parent_id of 1 (root)
com_guidedtours.tour.1 has the parent_id of the component
etc

Actual result

all of them have the same root, breaking inheritance in the permissions of a tour

System information (as much as possible)

Found the issue. I am writing a PR for it. The table class is missing the _getAssetParentId() to get the parent id of the component.
