Revert of Re-enable some HistoryApiTests

Revert of Re-enable some HistoryApiTests (patchset #1 id:1 of https://codereview.chromium.org/926283003/)

Reason for revert:
All of these tests are still flaky, so reverting it will re-disable the tests.

Original issue's description:
> Re-enable some HistoryApiTests
>
> Currently HistoryApiTest.Delete, HistoryApiTest.GetVisits, and HistoryApiTest.SearchAfterAdd are disabled. These do not flake or time out locally nor on the try bots, so this CL re-enables them.

No LGTM from a valid reviewer yet. Only full committers are accepted.
Even if an LGTM may have been provided, it was from a non-committer,
_not_ a full super star committer.
See http://www.chromium.org/getting-involved/become-a-committer
Note that this has nothing to do with OWNERS files.

Not sure... maybe only committers can TBR without an lg?  Don't know.
