This fixes #6093 UX component by disabling the rendering of internal datalad subdataset calls that would be reported to the user.
It also fixes its performance component by not running an additional subdatasets query when the target dataset has already been installed.

Before, a simple get of a subdataset looked like this:

❱ datalad  get -n HCP1200/102513 
subdataset(ok): HCP1200/102513 (dataset)
[INFO   ] Fetching ''                              
install(ok): /tmp/hcp/HCP1200/102513 (dataset) [Installed subdataset in order to get /tmp/hcp/HCP1200/102513]
subdataset(impossible): /tmp/hcp/HCP1200/102513 [path not contained in any matching subdataset]

Now, it looks like this:

datalad get -n HCP1200/104012 
[INFO   ] Fetching ''                              
install(ok): /tmp/hcp/HCP1200/104012 (dataset) [Installed subdataset in order to get /tmp/hcp/HCP1200/104012]

In case of a large hierarchy of subdatasets, the user would see one
subdataset(ok) result record per subdataset hierarchy level.
In the current implementation, the installation of a subdataset would
query subdatasets one time more than needed; By checking whether the
most recently installed subdataset is the target dataset and returning
when this is True, this change saves us one subdataset call.
