[OE-core] [PATCH] context: allow test execution with buildhistory unless version-going-backwards is present

[Leonardo Sandoval]

The proposed approach is not the best one as discussed by RP [1]:

""Just as another note, 

ERROR_QA_remove = "version-going-backwards"
WARN_QA_remove = "version-going-backwards"

doesn't work since we can't then enable this check and the test cases
test_buildhistory_buildtime_pr_backwards and test_buildhistory_diff then
fail."
