When some of builds were deleted from BuildHistory, TestNG Results Trend graph does not show all preceding builds anymore.

Steps to reproduce:
1. Make several builds (#1, #2, #3) with test results.
2. Make one more build (#4). Delete it manually from build History
3. Make few more builds (#5, #6) and see to graph.
*Expected result: *graph contains build #1, #2, #3, #5, #6 (all but deleted)

• Actual result: *graph contains only results after deleted one: #5, #6

Note: I use job to run tests only and deleting builds by hand sometimes required to cleanup history from false-failed builds (after incorrect changes in job settings, problems with network/environment during tests etc.)
