8287876: The recently de-problemlisted TestTitledBorderLeak test is unstable

[mrserb]

This is an update of the test which was de-problemlisted here.

Looks like the initial root cause of the issue was related to the last disposed frame which for some reason was not deleted from the memory, for that issue, the next bug was reported.
But that change also replaced the usage of weak references by the Runtime.getRuntime().freeMemory() which is not stable enough to verify the leak - its return values vary a lot.

This change returns the usage of weak references and tests only one instance of TitledBorder which is enough to verify the old bug.
