RFR: 1839: SKARA-1480 broke BridgeBotTests

[Erik Joelsson]

When changing all 'openjdk.java.net' references to 'openjdk.org', the BridgeBotTests broke, because we now have a different user mapping in those tests, which results in different Git hashes.

These tests have an assumeTrue condition in the @BeforeClass setup, which will skip if the HG server isn't available. The URL to hg.openjdk.org uses 'http', which hasn't worked since the migration to the new URL, but some time during the last few days, it started responding to 'http', which caused the tests to start running again, and subsequently fail.

This patch updates the Git hash to the new one being produced with the new user mapping, and changes the protocol to https for hg.openjdk.org, since that is the preferred one.
