Remove redundant revert-to-snapshot test option

This option is used to control how revert-to-snapshot
extra-spec is used when creating a share type for several tests,
but for the same tests, it is more appropriate to either not
create a share-type (thus use the default or "don't care"
behavior) or do so based on the value of
run_revert_to_snapshot_tests.

TrivialFix
