How to reproduce:
1. Open the attached project "bug-profiler-load-timings.zip" and scene "SampleScene"
2. Open the Profiler window
3. Enter Play Mode
4. Search for and inspect the "Look at me!" sampler
5. Exit Play Mode
6. Inspect the "Look at me!" sampler's values again
7. Save the recorded profile to disk
8. Load the saved profile
9. Inspect the "Look at me!" timings again

Expected result: timing percentages for "Look at me!" don't change after exiting Play Mode and are identical after saving and loading the profile
Actual result: timings for "Look at me!" during recording are much larger than after exiting Play Mode. Also, the values for "Look at me" are cleared when the profile is saved and loaded from disk

Reproducible with: 2017.4.27f1, 2018.4.1f1, 2019.1.5f1, 2019.2.0b4, 2019.3.0a4

Notes: it appears that the "Self" value of the "Look at me!" sampler is added to its parent's "Self" value when the profile is loaded from disk
