PT-2151 fix tests for pt-query-digest (#631)

* PT-2151 - Fix tests for pt-query-digest

Put fix for PT-1908 into the proper place

* PT-2151 - Fix tests for pt-query-digest

Put fix for PT-1554 into the proper place

* PT-2151 - Fix tests for pt-query-digest

Adjusted expected results for the default test t/pt-table-checksum/basics.t, so they do not depend on number of rows in the help tables

* PT-2151 - Fix tests for pt-query-digest

Added additional check for both replicas into t/pt-online-schema-change/preserve_triggers.t to avoid deadlock when ->ok() is doing CHECKSUM

* PT-2151 - Fix tests for pt-query-digest

Added delay to t/pt-table-sync/wait.t, so it waits for the child process to start lagging

* PT-2151 - Fix tests for pt-query-digest

Updated t/pt-query-digest/samples/issue_1196-output-8.0.txt, so it reflects changes in the latest 8.0

* PT-2151 - Fix tests for pt-query-digest

Updated queries against query history table, so they don't fail after e2cf183762

* PT-2151 - Fix tests for pt-query-digest

Fixed PT-813 by comparing query text. Since order itself does not matter, it is not essential to compare by the fingerprint or use any other function that changes the query.

* PT-2151 - Fix tests for pt-query-digest

Adjusted samples files which now should have consistent order after fix for PT-813

* PT-2151 - Fix tests for pt-query-digest

Fixed typo in the SELECT query in the QueryReview package

* PT-2151 - Fix tests for pt-query-digest

Fix for PT-981

* PT-2151 - Fix tests for pt-query-digest

Updated modules for pt-index-usage and fixed tests, because checksum is calculated differently after fix for PT-1554

* PT-2151 - Fix tests for pt-query-digest

Updated modules for pt-diskstats, pt-fk-error-logger, pt-heartbeat, pt-online-schema-change, pt-slave-delay, pt-slave-find, pt-table-checksum, pt-table-sync, pt-upgrade

* PT-2151 - Fix tests for pt-query-digest

Updated lib/IndexUsage.pm, so fix for pt-index-usage is in the correct place

t/pt-index-usage/save_results.t
