Fix Wording of the Perform Calibration Message

[jisedlac]

When reproducing GH-175, a dialog with the following hint is eventually displayed:

To perform calibration, use "Tools | Options | Java | Profiler | General | Manage calibration data".

This wording is incorrect for VisualVM, should be : "Tools | Options | Profiling | Manage".

Fixed in master.
