Temporal testing fails for `:terminate_if_running` reuse policy

[iegomez]

When enabling testing, the gem runs this check on workflows:

temporal-ruby/lib/temporal/testing/temporal_override.rb

Line 141 in 5d12aa3

w_id == workflow_id && disallowed_statuses.include?(execution.status)

The problem is that disallowed_statuses (at

temporal-ruby/lib/temporal/testing/temporal_override.rb

Line 152 in 5d12aa3

def disallowed_statuses_for(reuse_policy)

) doesn't consider the valid terminate_if_running reuse policy, thus crashing at disallowed_statuses.include?(execution.status) due to it returning nil.
