As fancy as property paths are, recursive resolution of files
to a location increases the big O complexity enough that it's
not a great option on large homedirs with many indexed files.
Ensure the files are from the right location through a URI
prefix match, which does hits an index. This may dramatically
improve performance on large indexed trees.
Testing this query in an isolated testcase with a total
1434099 indexed files shows that it can run more than 1500 times
per second in this computer (an average of 15200 queries in
several 10 second runs), which presumably is a tad faster than
anyone can type.

Failure is allowed by nature of GInitable, and this avoids unnecessary
crashing of programs running with G_DEBUG=fatal-criticals.

Given it does seem likely Tracker is going to miss the goal to get all
applications ported to Tracker 3, the scenario where there's applications
linking to Tracker 2.x while GTK was built with Tracker 3 support becomes
more likely.
Avoid the upcoming GType clashes if that were the case, and resort to the
good (I lie) old Tracker 2 search engine.
Provide the minimal info necessary. Improves apparent responsiveness
(since we don't visibly clear and repopulate the list) and saves doing
file stat/reads on every file in the result set.
